    so a parabole to a line would mean a sharp turn right? so that means it wouldn't be differentiable at that point

    yes we have a parabola and then a line that would mean a sharp turn so it wouldn't be differentiable at (-2,13) for any value of a and b

    we have f(x)=x^2-4x+1 if x<=-2 so if x=-2 then f(-2)=13

    i mean, how do i find value of a and b ?

    there is no a and b that would make this function differentiable at x=-2 because there is a sharp turn since we have a parabola to a line if we were just trying to find a and b such f is continuous on the reals that would be possible
