Answer:

f(-7)= -21

f(13)= 99

Step-by-step explanation:

Find f(-7) and f(13) using this equation f(x)=3(2x+7).

To find f(-7) plug in -7 into all the x values in the equation.

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

Multiply 2 and -7.

f(-7)=3(-14+7)

Add -14 and 7.

f(-7)=3(-7)=-21

For f(13) plug in 13 to all the x values.

f(13)=3(2(13)+7)

Multiply 2 and 13.

f(13)=3(26+7)

Add 26 and 7.

f(13)=3(33)=99

Hope this helps!

If not, I am sorry.
