    Exercise \(\PageIndex{1}\)

    Sketch the graph of a continuous function \(f\) so that

    (a) \(f(1) = 3\), \(f '(1) = 0 \), and the point (1,3) is a local maximum of \(f\).

    (b) \(f(2) = 1\), \(f '(2) = 0 \), and the point (2,1) is a local minimum of \(f\).

    (c) \(f(5) = 4\), \(f '(5) = 0\), and the point (5,4) is not a local minimum or maximum of \(f\).

    Exercise \(\PageIndex{2}-\PageIndex{4}\)
