The 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 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? (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

tkhunny · Answer

If the zeros are x = 0 and x = 4, the maximum will be at x = (0+4)/2 = 2

You tell me.  It is useful information for you to utilize in answers the questions.

"What do the x-intercepts and maximum value of the graph represent? "

"What are the intervals where the function is increasing and decreasing"

"what do they represent about the sale and profit"

These are "understanding-the-problem" questions.  Let's see what you get.  It's not a calculation issue.  It's a think-about-it issue.
