Question
Consider the following polynomial functions. Answer parts a through f below.
f(x) = (x-7)(x-8)(x+9)
g(x) = x³ +2x²-x-2
h(x) = 3x³ +6x²-3x-6
a. What is the value of f(7)?
f(7)= 0 (Simplify your answer.)
b. For what values, other than 7, is f(x) = f(7)?
x = 8,-9 (Use a comma to separate answers as needed.)
c. Evaluate the following.
g(-1) =
g(1) = 0
g(-2)
