Math Problem Statement
Graph the function y = |x + 5|.
Solution
The function shown in the image is , which represents an absolute value function. Here's how to approach graphing it:
Steps to Graph :
-
Understand the absolute value transformation:
- The basic form of an absolute value function is , which creates a "V"-shaped graph with the vertex at the origin (0, 0).
- In , the graph is shifted horizontally by 5 units to the left. This shift is due to the inside the absolute value function. So the vertex of the graph will be at .
-
Identify key points:
- Vertex: .
- The graph opens upwards, as the absolute value function always outputs positive values for .
-
Shape of the graph:
- For , the function behaves like because the expression inside the absolute value is negative.
- For , the function behaves like .
-
Draw key points:
- Plot the vertex at .
- Plot additional points on either side of the vertex, such as and , and connect them to form the "V" shape.
-
Symmetry:
- The graph is symmetric around the vertical line .
