The x-intercept = (0, 0) and (8, 0), Rate of function is 50 and as the price of erasers increasing the company's profit increasing and when price of the eraser decreasing the price the company's profit decreasing.
<h3>What is a function?</h3>
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:
From the graph:
x-intercept = (0, 0) and (8, 0)
Maximum value of the graph = 270 at x = 4
Increasing in the interval x ∈ (0, 4)
Decreasing in the interval x ∈ (4, 8)
As the price of erasers increasing the company's profit increasing and when price of the eraser decreasing the price the company's profit decreasing.
Rate of function = (270-120)/(4-1) = 50
Thus, the x-intercept = (0, 0) and (8, 0), Rate of function is 50 and as the price of erasers increasing the company's profit increasing and when price of the eraser decreasing the price the company's profit decreasing.
