You work forty hours a week at a furniture store. You receive a $220 weekly salary, plus a 3% commission on sales over $5000. Assume that you sell enough this week to get the commission. Given the function
f(x) = 0.03x and g(x) = x – 5000, which of (f o g)(x) and (g o f)(x) represents your commission?
What is (f o g)(x)?
Are they inverses?
f(x) = root(3)(5x-1)+4 and g(x) = ((x+4)^3+1)/5
What is no.
