1. 1.1 Summation

2. Graph (6, -1) What are the intercepts? (0, 0) (8, 1) (1, 4)
(0, -2)
(2, -5)
(2, 5)
What are the intercepts?
What is the domain?
What is the range?
Is the RELATION a FUNCTION?
Why or why not ?

3. {(4,7),(0, 5),(21, 41),(-6, 0)} Is this relation a function?
What is the domain?
What is the range?
What are the intercepts?

5. Example: Translating Points
Perform the given translation on the point (–1, 2). Give the coordinates of the translated point.
1 units left and 3 units down
Show mathematically!
1.1a

6. translation 2 units down
Example
translation 2 units down
Identify important points from the graph and make a table.
X Y
1.1b

7. reflection across x-axis
Example
Use a table to perform the transformation of y = f(x). Use the same coordinate plane as the original function.
reflection across x-axis x y f
1.1b

8. b) Reflection across x axis
Perform each transformation of y = f(x). Use the same coordinate plane as the original function. Copy the original function. Create a table. You can do all on graph paper
1.1b
a) Translate 2 units up
b) Reflection across x axis
