2-102.
  1. For the function g(x) = x3 + x2 − 6x , find the value of each expression below. Homework Help ✎

    1. g(1)

    2. g(−1)

    3. g(−2)

    4. g(10)

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

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

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

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

x = −3, 0, 2

6

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