검증된 단계별 안내

Identify the properties of even and odd functions: An even function satisfies \( f(x) = f(-x) \) and an odd function satisfies \( g(x) = -g(-x) \).

Since \( g \) is an odd function, use the property \( g(-1) = -g(1) \).

Evaluate \( g(-1) \) using the table or given information.

Substitute \( g(-1) \) into the composition \( g(g(-1)) \).

Use the property of odd functions again to evaluate \( g(g(-1)) \) by finding \( g(-g(1)) \).

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Even and Odd Functions

Even functions are defined by the property f(x) = f(-x) for all x in their domain, meaning their graphs are symmetric about the y-axis. Odd functions satisfy the condition g(x) = -g(-x), indicating that their graphs are symmetric about the origin. Understanding these properties is crucial for evaluating compositions of such functions.

Function Composition

Function composition involves applying one function to the result of another, denoted as (f ∘ g)(x) = f(g(x)). In this context, evaluating g(g(-1)) means first finding g(-1) and then using that result as the input for g again. Mastery of this concept is essential for solving the problem at hand.

Evaluating Functions at Specific Points

To evaluate a function at a specific point, you substitute the point into the function's expression. For example, to find g(-1), you would look up the value of g at -1 from the provided table. This step is fundamental in determining the output of the function compositions required in the question.
