Question

Use the function below to find f(-2)

f(x)=3^x

A. -9
B. -6
C. 1/6
D. 1/9

Answer 1

To find f(-2), substitute -2 into the function f(x) = 3x. The answer is 1/9.

Step-by-step explanation:

To find f(-2), we substitute -2 into the function f(x) = 3x. This gives us f(-2) = 3(-2). Using the properties of exponents, we know that 3(-2) is equal to 1/(3 2), which simplifies to 1/9. Therefore, the answer is D. 1/9.

Answer 2

f(x) = 3^x
f(-2) = 3^-2
f(-2) = 1/(3^2) = 1/9
