Question

Consider the function below, f (x) =x^3 + 2x^2-x-2,

Plot x- and y- intercepts of the function

Answer 1

The x-intercepts are at x = -2, x = -1, and x = 1.

The y-intercept is at y = -2.

Explanation:

(a) Create a table containing a few values of x and y.

x y

-3 -8

-2 0

-1 0

0 -2

1 0

(b) Plot the points on your graph

They should look something the graph below.

The x-intercepts are at x = -2, x = -1, and x = 1.

The y-intercept is at y = -2.
