Math Problem Statement
The graph above is a transformation of the function f(x) = |x|. Write an equation for the function graphed above.
Solution
The graph shown in the image is a transformation of the function , which is a V-shaped graph with a vertex at the origin. Let's analyze the given transformation.
Observations:
- The original vertex of is at the origin, but in this graph, the vertex has shifted.
- The vertex of this new graph appears to be at , which indicates a horizontal shift by 2 units to the left and a vertical shift by 3 units down.
- The slope of the graph on both sides of the vertex is the same as , meaning there is no change in slope (no stretching or compression).
Transformation Rule:
The general transformation for an absolute value function is: Where:
- represents a horizontal shift (to the left if is negative),
- represents a vertical shift (down if is negative),
- affects the slope (since , there is no vertical stretch or compression).
Equation:
Here, the graph has shifted horizontally by 2 units to the left, so , and vertically by 3 units downward, so . Therefore, the equation is:
