A local store’s monthly revenue from T-shirt sales is modeled by the function [math]f(x) = –5x^2 + 150x – 7[/math].Use the equation and graph to answer the following questions: At what prices is the revenue increasing? Decreasing? What is the maximum revenue? What prices yield no revenue? Is the function even, odd, or neither?

[list=1] [*]Determine when the function is increasing and decreasing. [*]Determine the maximum revenue. [*]Determine the prices that yield no revenue. [*]Determine if the function is even, odd, or neither. [*]Use the graph of the function to verify that the function is neither odd nor even.
