Total profit P is defined as total revenue R minus total cost​ C, and is given by the function P(x)=R(x)−C(x). Find the total profit​ P(x) when ​R(x)=126.98x−0.5x2 and C(x)=3809.40+0.7x2.

Given:

The revenue function is

The cost function is

To find:

The profit function.

Solution:

We know that, the total profit P is defined as total revenue R minus total cost​ C.

So, the profit function is

Therefore, the profit function is .
