3. The graphs of two functions, f (r) and g(r), are shown below. The following questions concern the functions h. g and s defined as follows: Assume that the first and second derivatives of g(r) are defined everywhere. i.e. that g and g' are differentiable on (- infinity to infinity). Note that the graph of f(r) consists of line segments whose endpoints haw integer (whole number) coordinates. (a) For each of the following expressions, either find the exact value or explain why the expression is undefined. (b) On the interval [05,2], is s(r) always increasing, always decreasing, or neither? Explain your reasoning. (c) On the Interval [-0.5,0.5], is s(r) always concave up, always concave down, or neither? Explain your reasoning
