    i will type the whole question... in case... let f(x) = x^2 + ax + b. if f(1) = 6 and if f'(1)=-4, find the values of a and b and hence, find the local minimum point on y = f(x).

    f'(1) ususally denotes the derivative when x=1

    so f'(1) is just the derivitive of x^2 + ax + b?

    f' is teh derivative of that, the (1) means you replace x by 1 as usual
