Solution Steps

Step 1: Find the increasing intervals

The function is increasing when the graph goes up from left to right. This happens on the intervals (-∞, -7), (-5, -2), and (8, ∞).

Step 2: Find the local minima

Local minima are the lowest points in a small neighborhood on the graph. These occur at x = 3 and x = 7.

Step 3: Determine the sign of the leading coefficient

Since the graph rises to the right and falls to the left, the leading coefficient is positive.

Final Answer:

(a) (-∞, -7), (-5, -2), (8, ∞) (b) 3, 7 (c) Positive
