Question

1. Given f(x) = -3x - 2, find the following.
f(3)=
f(-1)=
f(-2)=

Answer 1

F(3)= -3(3)-2= -11
F(-1)= -3(-1)-2= 1
F(-2)= -3(-2)-2= -12

You’re basically just plugging in the values.

Answer 2

f(3)=-11

f(-1)=1

f(-2)=4

Step-by-step explanation:

For each question you would replace the x in the main equation (f(x)=-3x-2) for the number given within f(x).

Therefore,

f(3)=-3(3)-2

=-9-2

=-11

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

=3-2

=1

f(-2)=-3(-2)-2

=6-2

=4
