(gºf) means solve f(x) first, then use that for g(x)

f(x) = x +4 = -3 +4 = 1
Now replace the x in the equation for g(x) with 1
g(x) = x = 1
You have 2 apples, get 3 more, and then lose 2 of them.
So, you HAVE 2 apples, and if you get 3 more, you can add it to the 2.

In total at the moment, you have 5 apples. Now, you lose 2 more. We can subtract that from our total number of apples.

We now know that you are left with
3 apples.
