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.
Passing is a good goal.
pH = -log H+
7.2 = -log H+
-7.2 = log H+
10^(-7.2) = H+
Answer: H+ = 10^(-7.2), third choice

hope this helps!!
Yes, in a function you cannot have two different images for the same x.
Because if an x has more than one image, you couldn't tell what is the value of the image given that x.
