Part 1. using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are inverses.
f(x)=
x+a

b
g(x)=cx−d
part 2. show your work to prove that the inverse of f(x) is g(x).
part 3. show your work to evaluate g(f(
part 4. graph your two functions on a coordinate plane. include a table of values for each function. include 5 values for each function. graph the line y = x on the same graph.

Use the information given below, to compare the cost of operating two different vehicles for one month (4 weeks) you are considering two different cars. you drive to work, a 20 mile round trip, five days a week. gasoline costs you $1.50 per gallon car agets 28 miles per gallon, would have $300 a year in maintenance costs, and would cost you $1,500 per year to insure car b gets 19 miles per gallon, would have $500 a year in maintenance costs, and would cost you $1,000 per year to insure costs car a car b gas cost per month insurance cost per month maintenance cost per month $ total cost per month
