Here are the essential concepts you must grasp in order to answer the question correctly.
Function Composition
Function composition involves combining two or more functions to create a new function. If you have functions f(x) and g(x), the composition f(g(x)) means you apply g first and then apply f to the result. Understanding how to evaluate compositions is crucial for solving problems that involve multiple functions.

Evaluating Functions
Evaluating a function means substituting a specific input value into the function to find the output. For example, if h(x) is a function, then h(0) means you replace x with 0 in the function h. This process is essential for determining the values needed when working with function compositions.

Iterated Functions
Iterated functions refer to applying a function multiple times in succession. In the expression h(h(h(0))), the function h is applied three times, starting with the input 0. Understanding how to iterate functions is important for evaluating complex compositions and determining the final output.
