    Find the gradient at the following points at the given points?

    hi,
    i don't understand how i would find the gradient at the following points at the given points:

    y=3x^2-4x+1 at x=1

    i know i would start it:
    dy/dx=6x-4
    then substitute x to get:
    6-4=2

    would 2 be the gradient and that is all i do or is there more to do?

    thanks!

    That's correct and that's all you have to do. You have found the gradient of the tangent line in the point x=1 at the curve.
