F.M.A2HS.28: : Identify 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. Include recognizing even and odd functions from their graphs and algebraic expressions for them. Observe the effect of multiple transformations on a single graph and the common effect of each transformation across function types and use transformations to model situations.

F.M.A2HS.29: : Find inverse functions for simple polynomial, simple rational, simple radical, and use simple exponential functions. Solve 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.M.A2HS.30: : For exponential models, express as a logarithm the solution to a x b^(ct) = d, where a, c, and d are numbers and the base b is 2, 10, or e; evaluate the logarithm using technology.

4.1: : Summarize, represent, and interpret data on a single count or measurement variable.

SP.M.A2HS.31: : Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

4.2: : Understand and evaluate random processes underlying statistical experiments.

SP.M.A2HS.32: : Understand statistics as a process for making inferences about population parameters based on a random sample from that population. Compare theoretical and empirical results to evaluate the effectiveness.

SP.M.A2HS.33: : Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation.

SP.M.A2HS.36: : Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant. Recognize that some unlikely results can occur solely through randomness inherent in the system and "statistical significance" represents this likelihood. Make use of statistics as a way of dealing with, not eliminating, this inherent randomness.
