a. [tex]f(0) =[/tex]
b. [tex]f(1) =[/tex]
c. [tex]f(2) =[/tex]
d. [tex]f(-1) =[/tex]

Options:
A. 1, 9, 81, [tex]\frac{1}{9}[/tex]
B. 0, 1, 2, -1
C. 1, 9, 81, -9
D. 0, 1, 2, [tex]\frac{1}{9}[/tex]

Answer :

Final answer:

To evaluate the function f(x)=9x at the indicated values, substitute the values of x into the function.

Explanation:

To evaluate the function f(x) = 9x at the given values, we substitute the values of x into the function.

  1. f(0) = 9(0) = 0
  2. f(1) = 9(1) = 9
  3. f(2) = 9(2) = 18
  4. f(-1) = 9(-1) = -9

So, the exact answers are: a. 0, 9, 18, -9 and the simplified answers are: a. 0, 9, 18, -9.
