Step 1 Let

a)

Thus, f models the price of a computer after a discount of 400 dollars.

Also,

The function g gives a value that is 075 into x that is 75% of x.

This means that g gives only 75% of the regular price.

Therefore, g models the price of a computer after a 25 % discount.

b) To find composite function

By using

thus, the composite function

The composite function f(g(x)) models that the price of a computer has 25% discount and then 400 dollars discount.

c) To find composite function

By using

thus, the composite function

The composite function g(f(x)) models that the price of a computer has 400 dollars discount and then 25% discount.

d) Now find

Thus,

Hence

Hence the price of computer using function

Thus the composite function
