Step-by-step explanation:
DIVISION ALGORITHM: If and
are polynomials, and the degree of

To find you must:
Therefore,
Therefore,
Therefore,
We want to use the given functions to create another function that models the revenue of the worker as a function of the time he works.
The solutions are:
A) r(x) = x^2 - 150
B) $1,850
C) The difference quotient is equal to 2*x.
We have two functions:
f(x) = 36*x^2 - 150
f(x) is the amount of money that he wins for decorating x rooms.
g(x) = (1/6)*x
g(x) is the number of rooms that he decorates in x hours.
So the revenue as a function of time can be given by evaluating f(x) in g(x).
A) we get:
r(x) f( g(x)) = 36*[(1/6)*x]^2 - 150 = x^2 - 150
r(x) = x^2 - 150
B) If he works for 45 hours, we just need to replace x by 45 in the revenue equation:
r(45) = 45^2 - 150 = 1,875
Meaning that he would win $1,875 for 45 hours of work.
C) the difference quotient for a function f(x) is given by:
For the case of r(x) we have:
