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

Which of the following equations is represented by the graph? A. f(x) = |x + 3| + 2 B. f(x) = |x + 3| - 2 C. f(x) = |x - 3| - 2 D. f(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:

  1. Vertex of the graph: The vertex of the V-shape appears to be at (3,2)(-3, 2). This means the absolute value function has been shifted horizontally to the left by 3 units and vertically up by 2 units.

  2. 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 f(x)=axh+kf(x) = a|x-h| + k, where:

  • (h,k)(h, k) is the vertex,
  • aa 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 (3,2)(-3, 2), so the equation must involve x+3|x + 3| and a vertical shift by 2 units upwards.
  • Thus, the correct equation is f(x)=x+3+2f(x) = |x + 3| + 2.

Therefore, the correct answer is:

A. f(x)=x+3+2f(x) = |x + 3| + 2

Would you like more details or have any other questions?

Here are some related questions to deepen your understanding:

  1. How would the equation change if the graph opened downwards?
  2. What effect does changing the slope value aa have on the graph?
  3. How would you describe the graph of f(x)=x32f(x) = |x - 3| - 2?
  4. What is the domain and range of the given absolute value function?
  5. How would a vertical stretch affect the graph of f(x)f(x)?

Tip: The vertex form of an absolute value function f(x)=axh+kf(x) = a|x-h| + k allows you to easily identify shifts and transformations of the graph.
