**1.**

y = f(x)

When x = -8 , f(x) = 4 , and 4 is positive, so when x = -8 , f(x) is positive.

The function is positive at any point above the x-axis.

The function is positive on the intervals [-8, -6) and (-2, 4)

**2.**

The relative minimum is the y-coordinate of the low point on the graph.

The relative minimum is -5 .

**3.**

The function is increasing when its slope is positive.

The function is increasing on the intervals (0, 1) and (2, ∞)
