Question

Hi

My friend is stuck with her homework and me being older and British has no idea what she is talking about. She wants to know:

What is h(t) if h(x)= 9x^9 - 4x^4 + 3x - 2

Any hints will be appreciated. I don't require an answer, just some guidance please.

Thanks

Answer 1

Given: h(x) = 9x^9 - 4x^4 + 3x - 2

Just substitute t for x;

h(t) = 9t^9 - 4t^4 + 3t - 2

That's it!
