PLS HELP ILL MARK U BRAINLIEST The graph below shows a company's profit f(x), in dollars, depending on the price of pencils x, i
BartSMP [9]

Answer:Part A) see the explanation

Part B) see the explanation

Step-by-step explanation:

The picture of the question in the attached figure

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?

Let

x ----> the price of pencils in dollars

f(x) ----> a company's profit in dollars

we know that

The function f(x) is a quadratic function having x-intercepts at (0,0) and (10,0)

The x intercepts give us the price when profit is zero, so the x-intercepts represent break-even points

The vertex is at (5,160)

f(x) represent a vertical parabola open downward

The vertex is a maximum

The x-coordinate of the vertex represent the price of the pencils when the value of the profit is maximum

The y-coordinate of the vertex represent the maximum profit

therefore

The maximum profit of $160 is when the price of the pencils is $5

Profit is increasing on the interval (0,5) and decreasing on the interval (5,10)

This represents that profit is increasing when selling price ranges from 0 dollars to 5 dollars, then decreases when selling price is 5 dollars to 10 dollars

Part B: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent?

Find the average rate of change of the graph from x = 2 to x = 5

To find the average rate of change, we divide

X+2/4 = 3/8 solve for x
Anna007 [38]

Answer:

<h3>X=-1/8=-0.125</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

x+2/4=3/8

2/4=1/2 (First, use the common factor of 2.)

x+1/2=3/8

x+1/2-1/2=3/8-1/2 (Then, subtract 1/2 from both sides.)

3/8-1/2 (Solve.)

3/8-1/2=-1/8

-1/8=-0.125

x=-1/8=-0.125

In conclusion, the final answer is x=-1/8=-0.125.
