I have a problem and I need some help:- "For this function, find the value(s) of x at which dy/dx=0 f(x)=3x^2 - 12x + 13 For this function, find dy^2/d^2x." Any help would be greatly appreciated!!

Any help would be greatly appreciated!! where, exactly, are you having a problem? are you saying that you cannot find f'(x) ?
Right! I know that I am supposed to set the 1st derivative of that function equal to zero and solve for x but I am having trouble doing this! Any ideas?
Use the formula If $\displaystyle y =x^n \Rightarrow \frac{dy}{dx}= nx^{n-1}$ Does this help?
