If f(x)= x+2, g(x)=-4x+3, and h(x)=x^2-zx+1 find each value.
1. (f x g x h)(3)
2. (h divided by (f times g)(-6)
3.[ g o (h o f)](-4)
I don't think you really want a "z" floating around. I'll assume you meant a "2".
The first two are just straightforward multiplication and division. You can surely do those.
(g◦(h◦f))(-4)
= g(h(f(-4))
= g(h(-2))
= g(9)
= -33
