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
