Graphing Quadratic Equations in Two Variables · Exercise 47

In the previous set of exercises, you worked with the quadratic equation $R = - x^{2} + 40 x$ that modeled the revenue received from selling computers at a price of $x$ dollars. You found the selling price that would give the maximum revenue and calculated the maximum revenue. Now you will look at more characteristics of this model.
ⓐ Graph the equation $R = - x^{2} + 40 x$ . ⓑ Find the values of the x-intercepts.
