f(x)= x^2 +1 . g(x) = 1/x-4^2 and h(x)=sqrt(5x). Find the formula for f(g(h(x). I forgot how to do this :/

Answer 1

plug h(x) into g(x) for x...

Answer 2

I know... Im having problem simplifying it .'

Answer 3

I end up with (1/ (sqrt(5x) - 4^2) + 1, do i radicalize it?

Answer 4

take the result and plug it into f(x) for x

Answer 5

you skipped a step...

Answer 6

ah I just saw what you wrote, alright ill take it 2 function at the time. THanks

Answer 7
