Standards

ACT College and Career Readiness Standards - Mathematics (6-12)
AF303: Relate a graph to a situation described qualitatively in terms of familiar properties such as before and after, increasing and decreasing, higher and lower
AF604: Given an equation or function, find an equation or function whose graph is a translation by a specified amount up or down
F702: Build functions for relations that are exponential
S506: Recognize that when a statistical model is used, model values typically differ from actual values
Oklahoma Academic Standards Mathematics (Algebra 1)
A1.F.1.5: Interpret graphs as being discrete or continuous.
A1.F.2.1: Distinguish between linear and nonlinear (including exponential) functions. Understand that linear functions grow by equal intervals (arithmetic) and that exponential functions grow by equal factors over equal intervals (geometric).
A1.F.2.2: Recognize the parent functions f(x) = x and f(x) = |x|. Predict the effects of vertical and horizontal transformations f(x + c) and f(x) + c, algebraically and graphically.
A1.D.1.2: Collect data and analyze scatter plots for patterns, linearity, and outliers.
A1.D.1.3: Make predictions based upon the linear regression, and use the correlation coefficient to assess the reliability of those predictions using graphing technology.
Oklahoma Academic Standards for Mathematics (Grade 8)
PA.A.1.1: Recognize that a function is a relationship between an independent variable and a dependent variable in which the value of the independent variable determines the value of the dependent variable.
PA.A.1.2: Use linear functions to represent and explain real-world and mathematical situations.
Oklahoma Academic Standards for Mathematics (Grades 9, 10, 11, 12)
A1.A.2.1: Represent relationships in various contexts with linear inequalities; solve the resulting inequalities, graph on a coordinate plane, and interpret the solutions.
A1.A.4.4: Translate between a graph and a situation described qualitatively.
A1.F.1.2: Identify the dependent and independent variables as well as the domain and range given a function, equation, or graph. Identify restrictions on the domain and range in real-world contexts.
A1.F.2.1: Distinguish between linear and nonlinear (including exponential) functions arising from real-world and mathematical situations that are represented in tables, graphs, and equations. Understand that linear functions grow by equal intervals and that exponential functions grow by equal factors over equal intervals.
A1.D.1.2: Collect data and use scatterplots to analyze patterns and describe linear relationships between two variables. Using graphing technology, determine regression lines and correlation coefficients; use regression lines to make predictions and correlation coefficients to assess the reliability of those predictions.
Oklahoma Academic Standards: English Language Arts (Grade 11)
11.2.R.1: Summarize the main ideas and paraphrase significant parts of increasingly complex texts.
