This Question: 1 pt Use the definition of inverses to determine whether f and g are inverses. )35 Are the f and g inverses of each other? O No O Yes Cick to select your answer

Solution

f(x) = 3x - 15

g(x) = x/3 + 5

finding (fog)(x) and (gof)(x)

(fog)(x) = 3(x/3+5) - 15

= x

(gof)(x) = (3x -15) / 3 + 5

= x

so (fog)(x) = (gof)(x) = x

hence,they are inverses of each other

answer is YES
