What you need to know in this problem is if you ever are given g of h of something, what they're just telling you to do is g of x divided by h of x.
00:12
So i think that's what i would do first, is write out that formula.
00:16
It's just 2x squared minus 5 over.
00:20
It looks like negative 3x plus 5, but the screen is pretty small.
00:24
So when they ask you to do g over h of 4, well then you need to plug in 4.
00:31
And for both exits.
00:34
And just make sure that you do everything on top first.
00:39
So 4 times 4, 16 times 2 is 32, minus 5 is 27.
00:45
And then you end up with negative 12 plus 5, which is negative 7.
00:50
And i would just leave my answer like that...
