In Exercises 95–96, let f and g be defined by the following table: Find |ƒ(1) − f(0)| − [g (1)]² +g(1) ÷ ƒ(−1) · g (2) .

검증된 단계별 안내

Step 1: Identify the values of f(x) and g(x) from the given table for the specific inputs. Look up f(1), f(0), f(-1), g(1), and g(2) in the table provided in the problem.

Step 2: Compute the absolute difference |f(1) - f(0)|. Subtract f(0) from f(1), then take the absolute value of the result.

Step 3: Square the value of g(1). This means calculating [g(1)]² by multiplying g(1) by itself.

Step 4: Divide g(1) by f(-1). Perform the division g(1) ÷ f(-1). Ensure that f(-1) is not zero to avoid division by zero.

Step 5: Substitute all the computed values into the expression |f(1) - f(0)| - [g(1)]² + g(1) ÷ f(-1) · g(2). Simplify the expression step by step to reach the final result.

주요 개념

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

Function Evaluation

Function evaluation involves substituting a specific input value into a function to determine its output. For example, if f(x) is a function, then f(1) means to find the output of f when the input is 1. Understanding how to evaluate functions at given points is crucial for solving problems that require calculating specific values from a function.

Order of Operations

The order of operations is a set of rules that dictates the sequence in which mathematical operations should be performed to ensure consistent results. Commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), this concept is essential for correctly simplifying expressions and solving equations, especially when multiple operations are involved.

Absolute Value

Absolute value refers to the distance of a number from zero on the number line, regardless of direction. It is denoted by vertical bars, such as |x|, and is always non-negative. Understanding absolute value is important for interpreting expressions that involve differences between function outputs, as it affects the final result by ensuring it is expressed as a positive quantity.
