Acompany that sells phones generates revenue given by the function
r(x) = x2 + 20x + 50 (where x is the number of phones produced per month). the cost of production is given by the function c(x) = 50x + 30. which function gives the profit earned by the company?

Step-by-step explanation:

A company that sells phones generates revenue given by the function,

Revenue Function:  

where, x is the number of phones produced per month

The cost of production is given by the function.

Cost Function:

We need to find profit function of the company

Profit = Revenue - Cost

Let profit function be P(x)

Hence, The profit function of the company is

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
