Answer 4

increasing

Answer 5

is it increasing on all real numbers though?

Answer 6

Looks like it's increasing everywhere in the graph.

Answer 7

ok, how do you determine if its:
Increasing on x < 0; Decreasing on x > 0
OR
Increasing on x > 0; Decreasing on x < 0

Answer 8

Whenever the graph looks like it's pointing downward, it's decreasing. Meaning the slope is negative.

Answer 9

alright, but what does the increasing on x<0 and decreasing on x>0 mean?

Answer 10

That's the part where the function is increasing.
