Find an equation for the inverse of the following relation.

y=2/3 x+5

Afunction is given: f(x)=3x+12 a. determine the inverse of this function and name it g(x) b. use composite functions to show that these functions are inverses. c. f(g(– explain: what is the domain?

This is so hard and it’s for a test

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)
