is there a way to do a screenshot where I can see all of #1 (the question plus all possible answer choices)?

The answer to #1 looks right, but there may be a better answer. 

Also, the question you have for #2 looks like an answer to some other question (maybe question 1?)

#4 is missing the question

anonymous · Answer

http://prntscr.com/8bz8nh Thanks, I have no idea why all the questions are missing.

jim_thompson5910 · Answer

you made a common mistake that many students make

the x+2 inside the vertical bars doesnt' mean you go 2 units right
you actually go 2 units to the left

Ahh, that is a bit unusual. I greatly appreciate your help!

jim_thompson5910 · Answer

yeah it's opposite because the shift from f(x) to f(x-h) moves the graph h units to the right
