Math Problem Statement
Which of the following equations is represented by the graph?
A.
f(x)=|x+3|+2f(x)=|x+3|+2
B.
f(x)=|x+3|−2f(x)=|x+3|-2
C.
f(x)=|x−3|−2f(x)=|x-3|-2
D.
f(x)=|x−3|+2f(x)=|x-3|+2
Solution
The graph provided shows a V-shaped curve, which is characteristic of an absolute value function. To determine the equation that represents the graph, we need to analyze a few key features:
-
Vertex of the graph: The vertex of the V-shape appears to be at . This means the absolute value function has been shifted horizontally to the left by 3 units and vertically up by 2 units.
-
Orientation and slope: The graph opens upwards, indicating a positive slope, and there are no reflections.
The general form of an absolute value function is , where:
- is the vertex,
- controls the steepness (which here seems to be 1 since the slopes on either side of the vertex rise at a 45-degree angle).
Step-by-Step Analysis:
- The vertex is , so the equation must involve and a vertical shift by 2 units upwards.
- Thus, the correct equation is .
Therefore, the correct answer is:
A.
