Domain: Functions
Theme: Define, evaluate, and compare functions
Description: Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
If y = (x - 4)2, find the value of y when x = 5.
