Let the expense function for a particular item be defined as y = –1,950x + 53,000. Let the revenue function be defined as y = –450x² + 10,000x , where x represents price in each equation. Use the window on the right.
a. Graph the two functions.
b. Determine the x- and y-coordinates of the first point where the two graphs intersect. Round those values to the nearest whole number.
c. Explain the significance of this point in the context of expense, revenue, and price.
