검증된 단계별 안내

Step 1: Identify the vertical asymptotes by setting the denominator equal to zero and solving for x. For the function $ f(x) = \frac{x^2 - 2x + 5}{3x - 2} $, set $ 3x - 2 = 0 $ and solve for x.

Step 2: Determine the horizontal asymptote by comparing the degrees of the numerator and the denominator. Since both the numerator $ x^2 - 2x + 5 $ and the denominator $ 3x - 2 $ are polynomials of degree 2 and 1 respectively, divide the leading coefficients.

Step 3: Find the x-intercepts by setting the numerator equal to zero and solving for x. Solve $ x^2 - 2x + 5 = 0 $ to find the x-intercepts.

Step 4: Use a graphing utility to plot the function $ f(x) = \frac{x^2 - 2x + 5}{3x - 2} $ and its asymptotes. Observe the behavior of the graph near the asymptotes.

Step 5: Sketch the graph by hand, ensuring to correct any discrepancies observed in the computer-generated graph, particularly around the asymptotes and intercepts.

주요 개념

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

Asymptotes

Asymptotes are lines that a graph approaches but never touches. They can be vertical, horizontal, or oblique. Vertical asymptotes occur where the function is undefined, typically where the denominator equals zero. Horizontal asymptotes describe the behavior of a function as x approaches infinity, indicating the value the function approaches. Understanding asymptotes is crucial for accurately sketching the graph of rational functions.

Graphing Rational Functions

Graphing rational functions involves plotting the function defined as the ratio of two polynomials. Key steps include identifying intercepts, asymptotes, and the end behavior of the function. The numerator's degree relative to the denominator's degree influences the graph's behavior at infinity. Using a graphing utility can help visualize these features, but manual sketching allows for correction of any inaccuracies in the computer-generated graph.

End Behavior

End behavior refers to the behavior of a function as the input values approach positive or negative infinity. For rational functions, this is determined by the degrees of the numerator and denominator. If the degree of the numerator is less than that of the denominator, the function approaches zero. Conversely, if the degrees are equal, the function approaches the ratio of the leading coefficients. Understanding end behavior is essential for predicting how the graph behaves far from the origin.
