Question

Given f(x) = 3x + 2, find f(-4).

Answer 1

f(-4)= -10

Explanation:

You should substitute x with -4 in f(x)

f(-4)= -12+2= -10

Answer 2

f(-4) = -10

Step-by-step explanation:

Easy one!

You just have to replace x by -4. That's it!

f(-4) = 3(-4) + 2,

f(-4) = -12 + 2,

f(-4) = -10

And voila!
