The manager of a hardware store sells batteries for $5 a package. She wants to see how much money she will earn if she increases the price
in 10¢ increments. A model of the price change is the revenue
function R(x) = – x2 + 10x + 3000, where x is the number of
10¢ increments and R(x) is in dollars. Explain how to determine the
maximum revenue.

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)
