## Special functions

Absolute Value Function

### Absolute Value Function

f (x) =

Domain, range, x-intercept, y-intercept, vertex

Exercises:

Sketch the graph of the following and find the domain, range, vertex, and x and y-intercepts:

f (x) =

2. y =

3. y =

4. y = + 1

5. f (x) = - 1

Seatwork:

Sketch the graph of the following and find the domain, range, vertex, and x and y-intercepts:

f (x) =

2. y = + 2

y = + 3

y = - 2

y =

y =

3. f (x) = - 1; when 1x  -3
