2. Graphs of Equations

Graph each equation in Exercises 13 - 28. Let x = - 3, - 2, - 1, 0, 1, 2, 3

y = x³ - 1

In Exercises 27–38, evaluate each function at the given values of the independent variable and simplify.g(x) = x² + 2x + 3 a. g(-1)

Use the graph to a. determine the x-intercepts, if any; b. determine the y-intercepts, if any. For each graph, tick marks along the axes represent one unit each.

Use the graph to a. determine the x-intercepts, if any; b. determine the y-intercepts, if any. For each graph, tick marks along the axes represent one unit each.

Write each English sentence as an equation in two variables. Then graph the equation. The y-value is three decreased by the square of the x-value.

Write each English sentence as an equation in two variables. Then graph the equation. y = 5 (Let x = -3, - 2, - 1, 0, 1, 2, and 3.)

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. See Example 5. ƒ(x)=x³-x+9

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

Find g(-4)

Graph each function.

$\text{ƒ}\left(x\right)=-\text{√}x-2$

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