The pear company sells pphones. The cost to manufacture x pPhones is C(x)= -21x^2+52000x+21087 dollars (this includes overhead costs and production costs for each pphones). If the company sells x pphones for the maximum price they can fetch, the revenue function will be R(x)= -27x2+19600x dollars. How many pphones should the pear company produce and sell to maximize profit?

2,700 phones should the pear company produce and sell to maximize profit.

Step-by-step explanation:

The cost to manufacture x phones :

The revenue function will be :

The profit = P(x) = R(x) - C(x)

Differentiating P(x) with respect to dx;

x = 2,700

Differentiating with respect to dx again;

(maxima)

2,700 phones should the pear company produce and sell to maximize profit.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

14

step-by-step explanation:

14 x 3 = 42
