1. Suppose f(x) = x + 5 / x - 8 and g (x) = sqroot(x)

a. What is the domain of f?

b. Find g(f(x)). State it's domain.

c. Find f(g(x)). State it's domain.

d. Find the domain of h(x) = sqroot(x+5) / sqroot(x-8)

Also, is h the same function as the function you found in part b? Explain.

Thanks sooo o much
