Questions: The right side of a tower has a shape that can be approximated by the graph of the function defined by f(x)=-301 ln(x/207).
Answer parts (a) through (c).
(a) Explain why the shape of the left side of the tower has the formula given by f(-x).
A. The left side is a reflection of the right side with respect to the axis of the tower. The graph of f(-x) is the reflection of f(x) with respect to the x-axis
B. The left side is a reflection of the right side with respect to the axis of the tower. The graph of f(-x) is the reflection of f(x) with respect to the y-axis.
Transcript text: The right side of a tower has a shape that can be approximated by the graph of the function defined by $f(x)=-301 \ln \frac{x}{207}$.
Answer parts (a) through (c).
(a) Explain why the shape of the left side of the tower has the formula given by $f(-x)$.
A. The left side is a reflection of the right side with respect to the axis of the tower. The graph of $f(-x)$ is the reflection of $f(x)$ with respect to the $x$-axis
B. The left side is a reflection of the right side with respect to the axis of the tower. The graph of $f(-x)$ is the reflection of $f(x)$ with respect to the $y$-axis.
Solution
Solution Steps
Step 1: Analyzing the reflection
The tower is symmetrical with respect to the y-axis. The left side is a reflection of the right side across the y-axis.
Step 2: Reflection across y-axis
A reflection across the y-axis is represented mathematically by replacing x with -x in the function.
Final Answer:
The correct answer is B. The left side of the tower is a reflection of the right side with respect to the axis of the tower (the y-axis). The graph of f(-x) is the reflection of f(x) with respect to the y-axis.
