04.01 MC) Koel is the single producer of home air conditioners in its rural market. The firm's monthly demand is described by the equation P = 5000 − 5Q, where P is the price and Q is the quantity of units sold. Which of the following must be true of Koel?

An increase in price decreases the quantity sold.
It is a natural monopoly.
A decrease in price decreases the quantity sold.
Higher levels of output bring in increasingly lower total revenue if demand is elastic.
Maintaining the current price decreases the quantity sold over time.

Your answer is going to be d.

Dis the correct answer man

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

Ok i’m not good at this but imma try : )
