Preview Activity 3.3.1.
Consider the function \(h\) given by the graph in Figure 3.3.4. Use the graph to answer each of the following questions.
Figure 3.3.4. The graph of a function \(h\) on the interval \([-3,3]\text{.}\)
(a)
Identify all of the values of \(c\) such that \(-3 \lt c \lt 3\) for which \(h(c)\) is a local maximum of \(h\text{.}\)
(b)
Identify all of the values of \(c\) such that \(-3 \lt c \lt 3\) for which \(h(c)\) is a local minimum of \(h\text{.}\)
(c)
Does \(h\) have a global maximum on the interval \([-3,3]\text{?}\) If so, what is the value of this global maximum?
(d)
Does \(h\) have a global minimum on the interval \([-3,3]\text{?}\) If so, what is its value?
(e)
Identify all values of \(c\) for which \(h'(c) = 0\text{.}\)
(f)
Identify all values of \(c\) for which \(h'(c)\) does not exist.
(g)
True or false: every relative maximum and minimum of \(h\) on the interval \(-3 \lt x \lt 3\) occurs at a point \(c\) such that where \(h'(c)\) is either zero or does not exist. Explain your conclusion.
(h)
True or false: at every point where \(h'(c)\) is zero or does not exist on the interval \(-3 \lt x \lt 3\text{,}\) \(h\) has a relative maximum or minimum. Explain your conclusion.
