Use the vertical line test to identify graphs in which y is a function of x.

Determine whether each function is even, odd, or neither. ƒ(x)=x³-x+9

Let ƒ(x)=-3x+4 and g(x)=-x²+4x+1. Find each of the following. Simplify if necessary. ƒ(3t-2)

Use the graph of g to solve Exercises 71–76.

Find g(-4)

List the quadrant or quadrants satisfying each condition. x³ > 0 and y³ <0

In Exercises 77–92, use the graph to determine a. the function's domain; b. the function's range; c. the x-intercepts, if any; d. the y-intercept, if any; and e. the missing function values, indicated by question marks, below each graph.

In Exercises 85–90, find the x-intercepts of the graph of each equation. Then use the x-intercepts to match the equation with its graph. [The graphs are labeled (a) through (f).] y = 2(x + 2)^2 + 5(x + 2) - 3
