Question

F(x)=27-4x what is tue value of f(-5)

Answer 1

Answer: 47

Explanation:

This is asking you to substitute -5 for every "x" in your function.

So, f(-5)=27-4(-5)

f(-5) = 27+20

f(-5) = 47

Answer 2

f(-5) = 47

Explanation:

f(x) = 27 - 4x f(-5)

f(-5) = 27 - 4(-5)

f(-5) = 27 + 20

f(-5) = 47
