The graph below shows a company's profit f(x), in dollars, depending on the price of erasers x, in dollars, sold by the company

Graph of quadratic function f of x having x intercepts at ordered pairs 0, 0 and 8, 0. The vertex is at 4, 270.

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 = 1 to x = 4, and what does this rate represent? (3 points)

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

The x < 4 function is increasing to the vertex, x> 4 function is decreasing and approximate average rate of change of the graph is 70, and x ∈(0, 8) is the domain of the function.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a function shown in the picture.

Part A:

When the profit is zero, the x intercepts depict it. The biggest profit happens at the vertex, which has the highest value. The function increases until it hits the vertex, then decreases after that.

x < 4 function is increasing to the vertex.

x> 4 function is decreasing

Part B: approximate average rate of change of the graph from x = 1 to x = 4:

= [f(4) - f(1)]/(4-1)

= (270-60)/3

= 70

Part C: We can't sell pay individuals to take the thing since the domain is confined by x at x =0. We are constrained in terms of business at x=8.

Thus, the x < 4 function is increasing to the vertex, x> 4 function is decreasing and approximate average rate of change of the graph is 70, and x ∈(0, 8) is the domain of the function.
