Greeting, I am working on a short exercise for Business Calculus, and I need help understanding the topics of Elasticity of Demand and (Derivatives first & second graphs.) I have included a short exercise, so I can understand the topics better. Can you please help me solve and understand these problems.

Question #1 Topic: Elasticity of Demand

1. The price-demand equation for an order cf fries at a fast-food restaurant is: x + 10003: = 2500. Currently, the price of an order of fries in 50.99. If the price is decreased by 10%, will the revenue increase or decrease? Use elasticity to support your answer. \f3. Use the graph of f'(x) shown to the right to nd the following: a. Use the graph of PL!) to nd: f'(--1) = b. Use the graph of f'(x) to nd: f'( 2) = c. Use the graph of Fur) to identify the x-interval where Fur) :- 0. In the space below: d. Use the graph of {11) to create a sign chart for f'(I). e. Use the graph of f'(x) to create a sign chart for f \"(1'). f. Use the sign charts to sketch a Wynn of x)
