Math Problem Statement
Graph of y = |x + 1| - 2
Solution
To graph the equation , we can break down the transformations of the basic absolute value function .
Steps:
-
Basic Absolute Value Function: Start with , which is a V-shaped graph that has its vertex at the origin and opens upwards.
-
Horizontal Shift: The expression shifts the graph of 1 unit to the left. This means the new vertex is at .
-
Vertical Shift: The subtraction of 2 from the function, i.e., , shifts the graph 2 units down. This moves the vertex to .
Key Points:
- The vertex of the graph is at .
- The graph still maintains its V-shape, with the slope of the arms being 1 (the left arm slopes down at and the right arm slopes up at ).
Sketch of the Graph:
- Vertex:
- Left side: The slope is (goes down towards left).
- Right side: The slope is (goes up towards right).
This is the graph of , a V-shape shifted left and down from the basic graph.
