Question

An entrepreneur estimates that the total profit (profit = total revenue minus total cost) from his proposed company will be given by the function P(x) = x^3 – 4x^2 + 3x – 12, where P is in hundreds of dollars and x is the number of years elapsed after the company starts operations. In how many years (x) will the company break even (no profit, no loss)?

Answer 1

P(x) = x^3 – 4x^2 + 3x – 12

Answer 2

Four.
\[4^3-4(4^2)+3(4)-12=0\]
4^3= 64
4*4^2=64
3*4=12
64-64+12-12=0

Answer 3

so is it 4?

Answer 4

lol nevermind I'm so brain dead
