In this video, we are going to graph simple rational functions.
Let’s first make a table listing the x and y values
Plot the coordinate points on a coordinate plane. Note how there are no points on the x-axis.
In the second video, we are going to graph rational functions with transformation.
Keep the following in mind during transformation:
|Add # to x||Moves Left|
|Subtract # from x||Moves Right|
|Add # to Function||Moves Up|
|Subtract # from Function||Moves Down|
|Multiply Function (Positive)||Each y-value is multiplied|
|Multiply by Function (Negative)||Each y-value is multiplied, flipped over y-axis|
A transformation from to , each point of the latter graph will be located two units above each point of the prior graph.
A transformation from to , each point of the latter graph will be located across the x-axis compared to each point of the prior graph.
