Pl help me Excel Elementary has a student teacher ratio of 20:1. This is shown in the function f(x)=20x, where x is the number of teachers and f(x) is the number of students. Which of the following numbers could be part of the domain of this function?

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?
