    Find A and B so that F(x) is a Differentiable Function

    UPDATE: My Math Teacher just said it was a typo, where he forgot to add a negative two, so that the piecewise function would be: f(x): Ax^2 - Bx - 2, X ≤ 1 Alnx + B, X > 1 Now solving it, I got A = -2 and B = -2.

    Find A and B so that F(x) is a Differentiable Function

    Probably should have put this in earlier as proof of the existence of the problem. Hopefully links are fine. Sorry if it isn't allowed. http://www40.zippyshare.com/i/3Pmk4c2p/82894/WIN_20170301_215129.JPG

    Yep, that's exactly what it says.

    Find A and B so that F(x) is a Differentiable Function

    Homework Statement Find the values of a and b that make f a differentiable function. Note: F(x) is a piecewise function f(x): Ax^2 - Bx, X ≤ 1 Alnx + B, X > 1 Homework EquationsThe Attempt at a Solution Made the two equations equal each other. Ax^2 - Bx = Alnx + B Inserting x=1 gives, A - B =...
