- A-CED.4Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.
A-REI Β· Reasoning with Equations & Inequalities
- A-REI.1Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
- A-REI.10Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).
- A-REI.11Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations.
- A-REI.12Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.

- A-REI.4.bSolve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a +/- bi for real numbers a and b.
- A-REI.5Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.

F-IF Β· Interpreting Functions
- F-IF.1Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
- F-IF.2Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
- F-IF.3Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers.
- F-IF.4For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.
- F-IF.5Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes.
- F-IF.6Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.

- F-IF.8.aUse the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.
- F-IF.8.bUse the properties of exponents to interpret expressions for exponential functions.
- F-IF.9Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).
F-BF Β· Building Functions
- F-BF.1.aDetermine an explicit expression, a recursive process, or steps for calculation from a context.
- F-BF.1.bCombine standard function types using arithmetic operations.
- F-BF.2Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.
- F-BF.3Identify the effect on the graph of replacing f(x) by f(x) + k, kf(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology.
- F-BF.4.aSolve an equation of the form f(x) = c for a simple function f that has an inverse and write an expression for the inverse.
F-LE Β· Linear, Quadratic & Exponential Models
- F-LE.1.aProve that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.
- F-LE.1.bRecognize situations in which one quantity changes at a constant rate per unit interval relative to another.
- F-LE.1.cRecognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.
- F-LE.2Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
- F-LE.3Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.
- F-LE.5Interpret the parameters in a linear or exponential function in terms of a context.
- F-LE.6Apply quadratic functions to physical problems, such as the motion of an object under the force of gravity.
S-ID Β· Interpreting Data
- S-ID.1Represent data with plots on the real number line (dot plots, histograms, and box plots).
- S-ID.2Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
- S-ID.3Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).
- S-ID.5Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.
- S-ID.6.aFit a function to the data; use functions fitted to data to solve problems in the context of the data.
- S-ID.6.bInformally assess the fit of a function by plotting and analyzing residuals.
- S-ID.6.cFit a linear function for a scatter plot that suggests a linear association.
- S-ID.7Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
- S-ID.8Compute (using technology) and interpret the correlation coefficient of a linear fit.
- S-ID.9Distinguish between correlation and causation.
