The graph below shows a company's profit f(x), in dollars, depending on the price of erasers 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?
Part B: If at one time the profit of the company was at least $120 what domain could possibly produce this profit?
Part C: What is an approximate average rate of change of the graph from x = 1 to x = 4, and what does this rate represent?

Best ResponseYou've already chosen the best response.0This is what I have for Part A: Part A: The xintercepts represent the prices when no prices were made and the maximum value represents the highest profit. The price increases until x = 4. Then the prices decreases when x is greater than 4. Is that correct??

Best ResponseYou've already chosen the best response.1for part B the profit minimum of 120 dollars is when the price x = 1 the domain would be 1 to 6 (1,6)

Best ResponseYou've already chosen the best response.0Ok so would it be 1 is greater than or equal to x which is less than or equal to 6?

Best ResponseYou've already chosen the best response.1sorry  the profit is 120 dallars for x = 7 so domain is (1,7)

Best ResponseYou've already chosen the best response.0ok thanks so much! For part c the rate of change would be 50 but what does it represent

Best ResponseYou've already chosen the best response.1i should have written it as [1,7] but what you wrote is fine.

Best ResponseYou've already chosen the best response.1i guess its the average increase of profit per unit increase of price of erasers.

Best ResponseYou've already chosen the best response.0A sandbag was thrown downward from a building. The function f(t) = 16t2  32t + 384 shows the height f(t), in feet, of the sandbag after t seconds: Part A: Factor the function f(t) and use the factors to interpret the meaning of the xintercept of the function. Part B: Complete the square of the expression for f(x) to determine the vertex of the graph of f(x). Would this be a maximum or minimum on the graph? Part C: Use your answer in part B to determine the axis of symmetry for f(x)? @welshfella
