Use the graph of y = f(x) to graph each function g. g(x) = -f(x-1) + 1

검증된 단계별 안내

Start with the original function \( y = f(x) \). The goal is to graph \( g(x) = -f(x-1) + 1 \) by applying transformations to \( f(x) \).

First, consider the inside of the function argument: \( f(x-1) \). This represents a horizontal shift of the graph of \( f(x) \) to the right by 1 unit.

Next, apply the negative sign in front of \( f(x-1) \), which means reflecting the graph of \( f(x-1) \) across the x-axis (flip it upside down).

Finally, add 1 to the entire function: \( -f(x-1) + 1 \). This shifts the graph vertically upward by 1 unit.

To summarize, start with the graph of \( f(x) \), shift it right by 1 unit, reflect it over the x-axis, then shift it up by 1 unit to obtain the graph of \( g(x) \).

주요 개념

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

Function Transformations

Function transformations involve shifting, reflecting, stretching, or compressing the graph of a function. In this problem, the function g(x) is derived from f(x) by applying horizontal shifts, reflections, and vertical shifts, which change the graph's position and orientation without altering its shape.

Horizontal Shifts

A horizontal shift moves the graph left or right. For g(x) = -f(x-1) + 1, the term (x-1) inside the function indicates a shift of the graph of f(x) one unit to the right. This means every point on f(x) moves right by 1 unit before other transformations are applied.

Reflections and Vertical Shifts

The negative sign before f(x-1) reflects the graph across the x-axis, flipping it upside down. The +1 outside the function shifts the entire graph up by one unit. Together, these transformations modify the graph's orientation and vertical position.
