Can you do D, E, and F please?

1. Suppose \( f \) is differentiable everywhere, \( f(0) = -1/2 \), and \( f' \) is graphed below.

[Left Graph: Blank grid with labeled x-axis at 1.]
[Center Graph: Graph of \( f' \) on the grid; features a curve that dips and rises, passing through y=-2 on the y-axis and approximately x=1 on the x-axis, labeled \( f' \).]
[Right Graph: Blank grid with labeled x-axis at 1.]

(a) Find all critical numbers of \( f \). If there are none, say so.

(b) Use the graph of \( f' \) to find all intervals on which \( f \) is increasing or decreasing.

(c) Use a test to classify each critical number of \( f \) as a local maximum, local minimum, or neither.

(d) Use the graph of \( f' \) to sketch a graph of \( f'' \) on the axes to the right of \( f' \).

(e) Use your graph of \( f'' \) to find where \( f \) is concave up, is concave down, and has inflection points.

(f) Use all this to sketch a graph of \( f \) on the axes to the left of \( f' \). Label local max/min and inflection points.
