Final answer:
The composition of the function h(x) with itself, denoted as (h ∘ h)(x), is √(√x + 1 + 1). This expression is a nested radical and cannot be simplified further without additional information.
Step-by-step explanation:
To find (h \circ h)(x) for the function h(x) = \sqrt{x + 1}, we need to evaluate the function h at the result of the function h(x). This means we will substitute h(x) back into itself.
First, compute h(x):
Then, compute h(h(x)):
- h(h(x)) = h(\sqrt{x + 1})
- = \sqrt{\sqrt{x + 1} + 1}
Now we have the composition of h with itself, which is:
(h \circ h)(x) = \sqrt{\sqrt{x + 1} + 1}
We cannot simplify this expression any further as it stands, since it's a nested radical and does not reduce to a simpler algebraic form without further context.
