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 pens x, in dollars, being 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 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: If at one time the profit of the company was at least $60, what domain could possibly produce this profit? (2 points) Part C: 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)

Best ResponseYou've already chosen the best response.1Part B: When y is 60 x is both 1 and 5 Part C: We have to look at x = 3 and x = 5 and find the 'y' values..which is 120 and 60 (3, 120) (5, 60) Plug them into the slope formula: m=y2−y1/x2−x1 m=60−120/5−3 Simplify

Best ResponseYou've already chosen the best response.0for B you are looking for a "domain", which here is the set of all the x values that go into your function to give a profit of **at least** $60. it's not 1 and 5.
