Question

For the function graphed below, identify the domain, range, intercepts, relative extrema, and end behavior. Find the intervals where the function is increasing and decreasing, and then find the intervals where the function is positive and negative.

Answer 1

Answer:

domain = (-∞,∞)

range = (-∞,∞)

y intercepts = (0,5)

x intercepts = (0,8)

increasing = (-∞,-8)∪(-4,2)∪(6,∞)

decreasing = (-8,-4)∪(2,6)

negative = (-∞,-2) or (-∞,-8)∪(-8,-2)

positive = (-2,∞)

Step-by-step explanation:

I'm pretty sure on everything but the negative because it does hit the x axis which makes the point (0,-8). But I'm pretty sure one of those is correct.
