Inverse Compositions

Determine whether g(x)=3x-6 and f(x)=1/3x+2 are inverses.

• yes

• no

Given that f(x) = 3x + 5 and g(x) = 1/3x + 5, find f(g(x)).  Are the two functions inverses of each other?

• x + 20 ; Yes they are inverses

• x + 20 ; No, they are not inverses

• x ; Yes they are inverses

• x ; No, they are not inverses
