The equation from past questions is R = 8x-0.02x^2

4. Since the equation you found is a parabola, it must have a maxi called the vertex Find the vertex 5. What does the vertex represent in the context of this activity? 6. When the students sell a taco, the money they receive is the revenue, but each taco costs money to make. The graph below shows the cost function. Graph the revenue function on the same graph. 3 ) 180 150 0 258 300 350 400 7. The break-even points are when the revenue is equal to the cost, R(x) = C(x). Find and mark the break-even points on the graph m question 6
