Math Problem Statement
Use the graph of y = f(x) to graph the function g(x) = -f(x) - 1.
Solution
To solve this problem, we are tasked with using the graph of to graph the function .
Step-by-Step Explanation:
-
Understanding the given graph:
- The graph of is a horizontal line segment from to , lying on the line .
-
Transformation for :
- The function is obtained from by applying two transformations:
- Reflection across the x-axis: This changes the sign of , so the values of will become positive where they were negative, and vice versa. For the given graph, since , for the same -values.
- Vertical translation by -1: After reflecting, we shift the graph down by 1 unit. This changes the value of to for the entire segment.
- The function is obtained from by applying two transformations:
-
Applying the transformation:
- The original line segment from to , which was at , will first reflect to , and then shift down by 1 unit to .
Matching the correct graph:
-
Looking at the options, the correct graph will have a horizontal line segment from to , positioned at .
-
Correct answer: Option D is the graph that corresponds to this transformation.
