Oh math Guru's I am just not getting how to find the limit of a composition with 2 graphs

The blue is g(x) and red f(x)

The graphs of and are given above. Use them to evaluate each quantity below. WriteDNEif the limit or value does not exist (or if it's infinity).

1.

2.

3.

4.

#2 and 3 are correct(#2=4 and #3=4) but I can't figure out 1 and 4 I thought #1 was 3 and #4 was 1

I understand where to look on the graph, I just don't understand how to relate the points to one another?
