Question

Function g is defined by g(x) = 3(x + 8). What is the value of g(12)?

a. -4
b. 20
c. 44
d. 60

Answer 1

To find the value of g(12), substitute 12 into the function g(x) = 3(x + 8), perform the addition, and then multiply by 3, resulting in a final value of 60.

Step-by-step explanation:

To find the value of the function g at x = 12, substitute 12 for x in the given function g(x) = 3(x + 8). Let's calculate it step by step:

1. Substitute 12 for x: g(12) = 3(12 + 8).
2. Perform the addition inside the parentheses: g(12) = 3(20).
3. Multiply 3 by 20: g(12) = 60.

Therefore, the value of g(12) is 60.
