Question

F(x)=x+3
f(-5) = ?
A-2 B-1 C-8 D7

Answer 1

the answer is f(-5)= -1

Answer 2

A. -2

Explanation:

f(x) is x+3.

When they add the number into the x part of f(x) they're just telling you to put that in for the equation

Since in this situation it's -5, all you have to do is add 3 to -5, which will result in -2.
