Lesson 2-5
Absolute Value Function
f(x) = | mx + b | + c where m cannot = 0.
f(x) = | 2x – 5 |
y = –|x + 3|.
Vertex- point where the function reaches a maximum on minimim. The vertex is located at (-b/m, c)
Find the vertex above.

3. Absolute Value Functions and Graphs
Graph y = | x |

4. Absolute Value Functions and Graphs
Lesson 2-5
Additional Examples
Graph y = |2x – 1| by using a table of values.
Evaluate the equation for several values of x.
x –1.5 –1 – y
Make a table of values.
Graph the function.

5. Absolute Value Functions and Graphs
