Answer 2

Answer:

$P(x)=x^2-30x+20$

Step-by-step explanation:

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

Revenue Function:  

$R(x)=x^2+20x+50$

where, x is the number of phones produced per month

The cost of production is given by the function.

Cost Function:

$C(x)=50x+30$

We need to find profit function of the company

Profit = Revenue - Cost

Let profit function be P(x)

$P(x)=R(x)-C(x)$

$P(x)=(x^2+20x+50)-(50x+30)$

$P(x)=x^2-30x+20$

Hence, The profit function of the company is $P(x)=x^2-30x+20$
