1) The regular price of a pair of jeans is x dollars. Let f (x) = x - 5; g (x) = 0.6x
a. Describe what functions f and g model in terms of the price of the jeans.
b. Find (f with g) (x) and describe what this models in terms of the price of the jeans.
(fog)(x) = f(0.6x) = 0.6x - 5
c. Repeat part (b) for ( G with f) (x)
(gof)(x) = g(x-5) = 0.6(x-5) = 0.6x - 3
d. Which composite function models the greater discount on the jeans, f wit g or g with f? Explain.
e. Find f to the "-1" power and describe what this models in terms of the price of the jeans.
f¯¹(x) = x + 5
