7. A piecewise function can be continuous everywhere but not differentiable everywhere. 8. If a function f(x) is continuous in an open interval, then f(x) has both a maximum value and a minimum value. 9. If the limit exists at x = a, then the function is continuous at x = a 10. If the left-hand limit and the right-hand limit of a function exist at a point x = a, then the limit at x = a exists.
