7-9.

Find the regions where each of the following functions is increasing, decreasing, concave up, and concave down. The points of inflection are included on the graph of to assist with concavity.

  1. Curve labeled, f of x, coming from lower left, passing through the point (negative 5, comma 0), turning down at about the point (negative 3, comma 8), turning up at (1, comma 2), turning down at (5, comma 8), passing through (7, comma 0), with highlighted points, (negative 1, comma 4), & (3, comma 4), where curve changes concavity.
