Question

Given f(x)=6(x-17)+5, what is f(12)?

Answer 1

When x = 12 in the function:

f(12) = 6((12) - 17) + 5
f(12) = 6(-5) + 5
f(12) = -30 + 5
f(12) = -25

f(12) = -25

Answer 2

f(12) = - 25

Explanation:

to evaluate f(12), substitute x = 12 into f(x)

f(x) = 6(x - 17) + 5 , then

f(12) = 6(12 - 17) + 5

= 6(- 5) + 5

= - 30 + 5

= - 25
