3.08: Function Operations 1 (F-BF-1b): Write a function that describes a
relationship between two quantities.
3.10: Function Inverses (F-BF-4a): Solve an equation of the form f(x) = c for a
simple function f that has an inverse and write an expression for the inverse. For example, f(x) = 2x3 or f(x) = (x + 1)⁄(x – 1) for x ≠ 1.
REMEMBER: We can’t get through EVERYTHING in class. Make sure you are reading the online lessons!
Be able add or subtract two functions
Understand what a function inverse is
Be able to find the inverse of a function
Subtracting two functions:
f(x) - g(x)
(f - g)(x)
Watch the order!
g(x) – f(x)
(g – f)(x)
Find (g - f)(x)
f(x) = 2x + 5 g(x) = -5x + 4
A function that can be used to model the cost of
producing x coffee mugs is c(x)= 12 + 8x, and the
function that can be used to model the amount
of money to be made from selling x coffee mugs
is m(x) = 17x + 2.
Write a function p(x) to represent the total
profit of selling x number of coffee mugs.
