I am finding the slope of a curve at a point. I am given the function and the point. For instance, I find the slope of the curve for y=x^2-3. No problem. But when we get into cubic equations, I don't know what to do. Instead of an h+3, for instance, I end up with a quadratic equation with h (h being delta x). Not sure what to do about this (first day of calculus!)
Thank you
