6) f(x) = 3 5x-9 If f(x) = (g oho k)(x) find g(x) and h(x) and k(x). 7) The graph below has f(x). Draw g(x) = -f(x) and h(x)= f(-x) and j(x) = -f(x + 3) and k(x) = f(3x) all on the same axes as f(x) and label them. 8) An international phone call costs $0.35 per minute for the first 20 minutes then $0.22 per minute for the next 40 minutes then $0.15 per minute for any additional minutes. Write a piecewise function for the cost of the phone call and then simplify to f(x) = mx +b form.
