Issac Grant · Answer 1

f ( - 2) = - 7

Step-by-step explanation:

To evaluate f ( - 2) substitute x = - 2 into f (x), that is

f ( - 2) = 5 ( - 2) + 3 = - 10 + 3 = - 7

Kareem Holt · Answer 2

In this question, you're solving the equation by plugging - 2 into x.

Plug - 2 into x:

f (x) = 5 (-2) + 3

Solve:

f (x) = 5 (-2) + 3

f (x) = - 10 + 3

f (x) = - 7

Answer:

f (x) = - 7
