Use the differentiability equation: f'(c) = lim x- f(x) f(c) x-c To determine whether or not f(x) = (x 3) (2+x) is differentiable at x = 3 If not, - state the type of non-differentiable point. If so, find the equation of the line tangent at x = 3 Be sure to show the results of the left and right derivatives. Round (final answers only) to the hundredths place, if necessary.
