Question

will fan and medal! :)

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:

Answer 1

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 to x = 4, and what does this rate represent? (3 points)

Answer 2

graph?

Answer 3

x intersept means break even point(4) andmaximu value=maximu profit

Answer 4

so, for part a?
I'd find the maximum value?

Answer 5

increase (-infinite;2) decrease (2;+infinite)

Answer 6

the question is what maximum value represents they don't ask to find it i guess

Answer 7

increase interval represents" when price goes up(so sale declines) then profit goes up(demand in this interval is inelastic)

Answer 8

decrease represents: when price goes up(after 2) sales decrease and profti decrease,because demand is elastic now

Answer 9

I'm lost? so for part a what do i put? do i just put what the x-intercept and maximum value represent?

Answer 10

in b it is 1dollar

Answer 11

the intervals for Part A are, 2?

Answer 12

the question is unclear there

Answer 13

they don't ask you to find maximum value they just ask you what it represents

Answer 14

then What are the intervals where the function is increasing and decreasing would that be, -2? and positive 2?
