This question is killing me. I'm finding it difficult to do and it's a problem with my homework.

Given that \(\displaystyle f(x)=2x^2-x+1,\,g(x)=2\sin(x)\text{ and }h(x)=3^x\), determine the following. You need not simplify the expressions.

\(\displaystyle f(g(-\pi))=?\)

\(\displaystyle \left(h^{-1}\circ f \right)(x)=?\)

\(\displaystyle g(f(h(x)))=?\)

I am so lost right now. Please help!
