w h(w) j(w)
2   4       1
3   9       1.5
4   16       2
9   81       4.5
16 256     8
j(w) means takeHalfOf(w)
h(w) means square(w)
So j(h(2) = 2 because h(2) = 4 because 2 to the 2 power is 4 and j(4) is half of 4 or 2 back for the answer.

So j(j(j(j(32)=2 because j(32) = 32/2 = 16 and j(16) = 16/2 = 8, and j(8) = 8/2 or 4. and j(4) is 2.

Ok I'm having a really hard time understanding this

I'll try to reproduce the graph

x     5   6    7     8      9
f(x)  8  7     5     8      6
g(x) 9   8    7     6      7


find f(g(6))

g(f(7))

f(f(6))

g(g(9))
