Absolute Value Function notes Keep in mind that the graph above does not show two lines intersecting What to remember for absolute value functions: 1. The absolute value of a linear function will create a "V" shape, naturally opening upward 2. If a negative sign is applied after calculating the absolute value, the "V" opens downward 3. When a constant is added on the outside of the bars a. If the constant is positive, the vertex shifts that many spaces up from the origin b. If the constant is negative, the vertex shifts that many spaces down from the origin 4. When a constant is added on inside the bars a. If the constant is positive, the vertex shifts left that many spaces from the y-intercept b. If the constant is negative, the vertex shifts right that many spaces from the y-intercept 5. Once you identify the location of the vertex, graph the function by creating a table of values that center around the vertex (choose 2-3 v-values above and below). This creates the best image.
