  1. Warm-Up! • Solve, graph and give the interval notation for:

  2. Algebra II – 2.6 Piecewise and Absolute Value Functions

  3. To Review: • Domain – the values of the X-coordinates needs to be found: • An interval is: • A piecewise function is drawn according to:

  4. Let’s Graph the following: 2 if f(x) = x + 4 if -½x if

  5. Graph: f(x) =

  6. Graph: f(x) =

  7. Graph: f(x) =

  8. Now let’s put it all together: o•-→q/

  9. Absolute Value Functions: • Remember that Absolute Value must always be • Therefore, the graph will always appear • No matter what value the X is, the Y will be

  10. Let’s Graph: First – set the value inside of the absolute value bars equal to zero Now that we have that X value where the graph is at its lowest point, we can find three greater and three less than that point Using a table –

  11. Graph the Coordinate Points:
