#### A2.F.2: Analyze functions through algebraic combinations, compositions, and inverses, if they exist.

A2.F.2.3: Find and graph the inverse of a function, if it exists, in real-world and mathematical situations. Know that the domain of a function f is the range of the inverse function f-¹, and the range of the function f is the domain of the inverse function f-¹.

A2.F.2.4: Apply the inverse relationship between exponential and logarithmic functions to convert from one form to another.

### A2.D: Data & Probability

#### A2.D.1: Display, describe, and compare data. For linear and nonlinear relationships, make predictions and assess the reliability of those predictions.

A2.D.1.1: Use the mean and standard deviation of a data set to fit it to a normal distribution (bell-shaped curve).

A2.D.1.2: Collect data and use scatterplots to analyze patterns and describe linear, exponential or quadratic relationships between two variables. Using graphing calculators or other appropriate technology, determine regression equation and correlation coefficients; use regression equations to make predictions and correlation coefficients to assess the reliability of those predictions.

#### A2.D.2: Analyze statistical thinking to draw inferences, make predictions, and justify conclusions.

A2.D.2.1: Evaluate reports based on data published in the media by identifying the source of the data, the design of the study, and the way the data are analyzed and displayed. Given spreadsheets, tables, or graphs, recognize and analyze distortions in data displays. Show how graphs and data can be distorted to support different points of view.
