2 Consider the function g(x) whose graph is given below. The domain of the function is contained in the interval [-3, 3], with f(-3) = f(3) = 0. +0.5- -2.5 +2.5 -0.5- -2.5- 1. What is the exact domain? 2. Are there points at which g is not continuous? If so, which are they, and why so? 3. Are there points a where lim >a g(r) does not exist? Which ones, and why? 4. On (approximately) which interval(s) is the derivative positive? Where does the derivative take the value zero? 5. On what interval(s) is the second derivative positive?)
