Question

The graph below shows a company's profit f(x), in dollars, depending on the price of goods x, in dollars, being sold by the company:

Unit 9 CR
Part A: What do the x-intercepts and maximum value of the graph represent in context of the described situation?

Part B: What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and profit for the company in the situation described?

Part C: What is an approximate average rate of change of the graph from x = 1 to x = 3, and what does this rate represent in context of the described situation?

Answer 1

Answer:The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, sold by the company:

Graph of quadratic function f of x having x intercepts at ordered pairs 0, 0 and 6, 0. The vertex is at 3, 120.

Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and profit? (4 points)

Part B: What is an approximate average rate of change of the graph from x = 3 to x = 5, and what does this rate represent? (3 points)
