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 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? 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?

This is what I have for Part A: Part A: The x-intercepts 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??

That appears to be right for Part A.

for part B the profit minimum of 120 dollars is when the price x = 1 the domain would be 1 to 6 (1,6)

Ok so would it be 1 is greater than or equal to x which is less than or equal to 6?
welshfella
  • welshfella
sorry - the profit is 120 dallars for x = 7 so domain is (1,7)

yes

ok thanks so much! For part c the rate of change would be 50 but what does it represent
welshfella
  • welshfella
i should have written it as [1,7] but what you wrote is fine.

ok thanks! What about C?

like what does it represent?

i guess its the average increase of profit per unit increase of price of erasers.

A 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 x-intercept 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
