Best ResponseYou've already chosen the best response.0The graph below shows a company's profit f(x), in dollars, depending on the price of notebooks x, in dollars, being sold by the company: Part A: What do the xintercepts 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? (5 points) Part B: At one time the profit of the company was at least $220, what domain could possibly produce this profit? (2 points) Part C: What is an approximate average rate of change of the graph from x = 2 to x = 4, and what does this rate represent? (3 points)

Best ResponseYou've already chosen the best response.1If the zeros are x = 0 and x = 4, the maximum will be at x = (0+4)/2 = 2

Best ResponseYou've already chosen the best response.1What do the xintercepts of the graph represent? That's where you're making ZERO profit. > What does the maximum value of the graph represent? That's where you're making MAXIMUM profit. > What are the intervals where the function is increasing and decreasing? The "function" (or more specifically, the y value of the graph) increases between x = {infinity,2} and decreases between x = {2,+infinity} > and what do they represent about the sale and profit? It means that your profit is dependent upon your price. Your profit will continue to rise up to the point that your price is $2, and then it will start to fall, and you can even start losing money if your price is too high (or too low)! > At one time the profit of the company was at least $220, what domain could possibly produce this profit? x would have to be between $1 and $3. > What is an approximate average rate of change of the graph from x = 2 to x = 4, and what does this rate represent? (y2  y1)/(x2  x1) = slope. (0  300)/(4  2) = slope (300)/(2) = slope 150 = slope
