I need some calculus help.
the profit (in millions of dollars) derived from selling x units of a certain software is modeled by the following function: P(x) = 0.003x^3 + 100x. If the rate of change in profit, called the marginal profit, is modeled by the derivative of P(x), find P'(x).

Best ResponseYou've already chosen the best response.0ok. if you have y = f(x) then the derivative of f is the function whose value is at the x limit

Best ResponseYou've already chosen the best response.0the way I think is best to think about a derivative is rate of change, it is the slope of the tangent line to some function at every point

Best ResponseYou've already chosen the best response.0if you think about it as this, then the first principle definition of a derivative is very natural

Best ResponseYou've already chosen the best response.0if you go close and close to the point. the slope of the secant line begins to approach the tangent line at that point

Best ResponseYou've already chosen the best response.0from this, we can write the first principle equation, and see why the power rule comes up

Best ResponseYou've already chosen the best response.0soo u want to know why the power rule came about?

Best ResponseYou've already chosen the best response.0when \[f(x) = x^n \] where n is any random number then \[f'(x) = n*x^{n1}\]

Best ResponseYou've already chosen the best response.0you can sub in x^n into first principle to see this formula come about

Best ResponseYou've already chosen the best response.0well if you are interested in the proof, you can try to work it out, you will have to use the binomial theorem in there
