If f(x)=x+7 and g(x)=1/x, what is (f•g)(x)?

Step-by-step explanation:

(f•g)(x) = f(g(x)) = f(1/x) = 1/x +7

3

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
