Define a function by:
(THIS IS A PIECEWISE FUNCTION):
h(x) = {0 if .. x^3 + 3x^2 if
1.) Determine which points h is continuous at, and determine which points h is discontinuous at. Prove these results.
2.) Determine which points h is differentiable at, and determine which points h is non-differentiable at. Prove these results.
