1. Lesson 9 Absolute Value as Distance Graphing Special Functions
Logs base 10 and natural base

2. Absolute Value of distance
| x – a | = d
What number is distance d from a?
a + d
a - d a

3. Absolute Value of distance
| x – a | < d
What number is distance less than d from a?
a + d
a - d a

4. Absolute Value of distance
| x – a | > d
What number is distance greater than d from a?
a + d
a - d a

5. Write down in notes!
3/5 + 2/5 = 1
3/5 – 2/5 =1/5
3/5

6. You try on white board

7. Special Functions Suppose you have a function f(x).
Then | f(x) | has the same graph of f(x) except when f(x)<0
If f(x) < 0, then the graph is reflected over the x-axis.
