Question

The function f is defined below.
f(x)=−2x−3
Find f(1).

Answer 1

`f(1)=-5`

Explanation:

`f(1)=-2(1)-3\\\\f(1)=-2-3\\\\f(1)=-5`

f(1) means to substitute x with 1 or that x=1. So since x=1 you will substitute it in where x is and then solve like a regular equation which will give you -5.
