45 POINT AND BRAINLIOEST HELP The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, 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 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? (4 points)

Part B: 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)

Part C: Describe the constraints of the domain. (3 points)

domains are negative and loose

Step-by-step explanation:

The 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:

The x intercepts give us the price when profit is zero

The maximum value gives us the maximum profit that can be reached.

Function is increasing from 0 to 3 and then decreasing from 3 to 6

Profit increases when price is 0 to 3 dollars, and profit decreases when price is 3 to 6 dollars.

Part B:

-26.67

The profit falls 26.67 dollars for every dollar increase of price , for prices between 3 and 5.
