We need to find the derivative of that equation with respect to x. The derivative of x^3 is 3x^2, the derivative of 3x^2 is 6x, and the derivative of any constant is always 0. Use the power rule for derivatives that says [tex] \frac{dy}{dx}( x^{n})=n*x ^{n-1} [/tex]. Our derivative, then, is [tex]3x^2+6x[/tex].
