Question

Evaluate the function f(-2) for the function f(x) = 3x + 10. What is the result?

Options:
A. f(-2) = -6
B. f(-2) = 4
C. f(-2) = 14
D. f(-2) = -16

Answer 1

To evaluate the function f(-2) for f(x) = 3x + 10, substitute -2 for x to get f(-2) = 3(-2) + 10, which simplifies to -6 + 10, and finally results in 4.

Step-by-step explanation:

The student is asked to evaluate the function f(-2) for the function f(x) = 3x + 10. To find f(-2), we substitute x with -2 in the function and calculate the result. To evaluate the function f(-2) for the function f(x) = 3x + 10, we substitute -2 for x in the function. So f(-2) = 3(-2) + 10. Simplifying this expression, we get f(-2) = -6 + 10 = 4.

f(-2) = 3(-2) + 10
= -6 + 10
= 4

Therefore, the correct option is B. f(-2) = 4.
