Question
Transcribed Image Text:3. The amount of money ($125 per day) paid to substitutes at LHS depends on how many
teachers are out; however it is not a direct relationship. Since teachers don't teach every block,
we can hire slightly fewer substitutes than there are teachers absent. Here are the functions
that are used to find the number of substitutes needed and the cost of substitutes per day.
f(x) = 0.8x + 2
and g(x) = 125x
If 20 teachers are absent one day, find out how much money LHS pays to
substitutes. Show your work.
а.
b. What order did you evaluate the functions and why did you do it that way?
C. What domain for the composition makes sense for this context?
d. If h(x) – f(x) = x³ – 6x + 12 , find h(x). Show work that leads to your answer.
