Question

Let f(x) = , then f is

Options

A.differentiable both at x = 0 and at x = 2
B.differentiable at x = 0 but not differentiable at x = 2
C.not differentiable at x = 0 but differentiable at x = 2
D.differentiable neither at x = 0 nor at x = 2

Solution




so, f(x) is differentiable at x = 0
f′(2+) =





Again, f′(2-) =
