Answer 3

| | means absolute value or in other words, only positive numbers
example | 4 | = 4 and | -4 | = 4 (negative numbers are turned into positive numbers)

so cross off any graph that has lines that show negative y values.

Answer 4

you are left with 2 choices.

Answer 5

to decide, let's ask "what is cot(0)?"
cotx = cos(x)/sin(x)
so cot 0 = cos(0)/sin(0)
cos(0)= 1 and sin(0)= 0
cot 0 = 1/0 (which is undefined by approaches infinity)
which graph shows a line zooming straight up near x= 0 ?
