For the function g(x) = x3 + x2 − 6x, find the value of each expression below. Homework Help ✎

1. $g(1)$

Substitute 1 for x in the given equation and then evaluate.

1. $g(−1)$

1. $g(10)$

1. Find at least one value of x for which g(x) = 0.

Let g(x) = 0 in the original equation and then solve for x.

x = −3, 0, 2

1. If f(x) = x2x + 3, find g(x) − f(x).

g(x) − f(x) = (x3 + x2 − 6x) − (x2x + 3)
