  1. Decreasing line passing through the point (2, comma 0) & the positive y axis.

  1. Increasing curve, coming from lower left, turning at the origin, changing from concave down to concave up at about x = 1, turning up @ x = 2 in fourth quadrant, passing through the point (3, comma 0), continuing up & right.

  1. Decreasing curve, coming from upper left, turning at the origin, changing from concave up to concave down at about x = 1, turning down @ x = 2 in first quadrant, passing through the point (3, comma 0), continuing down & right.

  1. Downward parabola, vertex at x = 1 & positive y, passing through the origin & the point (2, comma 0).

Upward parabola labeled, f prime of x, vertex at the point (1, comma negative 1, passing through the points (2, comma 0), & the origin.
