50 POINTS I'll mark you brainliest just please respond ASAP

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

Graph of quadratic function f of x having x intercepts at ordered pairs negative 0, 0 and 10, 0. The vertex is at 5, 160.

Part A: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent? (3 points)

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

if profit = f(x) then the x-intercepts represent the points at which profit = 0 for price x

maximum f(x) = maximum profit

the constraints of the domain are negative and loose

I hope I helped

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
