Determine if the function f(x) = Vx is differentiable at x = 0. If not, identify why. O f(x)=Vx' is not differentiable at x = 0 because lim x3 does not exist. vent O f(x)=Vx' is not differentiable at x = 0 because f(0) is not defined. O f(x) =Vx' is differentiable at x = 0. O f(x)=Vx' is not differentiable at x = 0 because f'(0) is not defined
