Is the graphed function differentiable at x 1 Choose the correct answer below OA Yes the function is differentiable at x 1 OB No because while the function is continuous at x 1 it does not have a tangent line at x 1 OC No because the function is not defined at x 1 OD No because while the function is defined at x 1 and lim exists lim is not equal to the value of the function at x 1 X 1 X 1 OE No because while the function is continuous at x 1 it has a vertical tangent line at x 1 OF No because while the function is defined at x 1 lim does not exist X 1 10 8 r 4 2 6 y 2
