Question

13. Solve the expression f(2) - g(-5) using the functions below.

f(x)= 3-4x
g(x)= -x + 7

Answer 1

-17

Explanation:

f(2)=3-4(2)

=3-8

=-5

g(-5)=--5+7

=12

f(2)-g(-5)=-5-12=-17

Answer 2

-17

Explanation:

f(x)= 3-4x

g(x)= -x + 7

f(2) = 3-4(2) = 3-8 = -5

g(-5) = -(-5) +7 = 5+7 = 12

f(2) - g(-5) = -5 - 12 = -17
