Question

Given the function f(x) = 3x + 1 what is f(-2)?

Answer 1

Answer:

-5

Step-by-step explanation:

f(-2) means that -2 is going to be our input in this function.

To solve this, simply substitute -2 for x in the expression given.

If f(x) = 3x+1, then f(-2) = 3(-2) + 1

3(-2)+1 = -6+1 = -5

Hope this helped!

Answer 2

Answer:

f(-2) = 3(-2) + 1

f(-2) = 6 + 7

Therefore: f(-2) = 7
