this is what I have so far

Answer 2

which question?

Answer 3

All of them. I was doing these with my dad, just want to know if I am on the right track

Answer 4

Q4 looks wrong. x->0+, the curve is going down to -infty

Answer 5

for Q1, tan(x) as you approach pi/2 from the positive (the right side) is going to negative infinity

Answer 6

My understanding is that a when they say ->0+ they mean that approaching 0 on the positive side, what is at the y

Answer 7

for Q4, x->0 means x is getting close to 0 (on the x-axis)
x->0+ means we are on the positive side (as you state), and approaching x=0
at x=1 the curve is at y=0, but that is not what you want.

Answer 8

So, when a question is asking what is the limit
what are they really asking?
