Graph

(6, -1) (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 ?

{(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?

Perform the given translation on the point (–4, -5). Give the coordinates of the translated point.

Example: Translating Points

5 units right, 2 units down

? Slope ?? Domain ?? Range ?

Show mathematically!

1 units left and 3 units down

Perform the given translation on the point (–1, 2). Give the coordinates of the translated point.

Example: Translating Points

Show mathematically!

Example

translation 2 units downIdentify important points from the graph and make a table.

X Y

reflection across x-axis

x yf

Example

Use a table to perform the transformation of y = f(x). Use the same coordinate plane as the original function.

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

a) Translate 2 units up

b) Reflection across x axis
