Short Answer

Graph y=x . Then on the same screen graph y=2x, followed by y=4x, followed by

y=12x.What pattern do you observe? Can you predict the graph ofy=14x? of y=5x

?

Graph of functions are

See the step by step solution

Step by Step Solution

Step 1. given data

The given functions are

y=xy=2xy=4xy=12xy=14xy=5x

Step 2. graph of the parent function

Plot the graph of the function y=|x|

Step 3. graph of the transformed function

Plot the graph of the function y=2|x| on the same Cartesian plane

graph of y=2|x| is equivalent to the vertically stretched graph of y=|x| by the factor 2

Step 4. graph of the transformed function 

Plot the graph of the function y=4|x|on the same Cartesian plane

graph of y=4|x| is equivalent to the vertically stretched graph of y=|x| by the factor 4

Step 5. graph of the transformed function 

Plot the graph of the functiony=12|x|on the same Cartesian plane

graph of y=12|x| is equivalent to the vertically compressed graph ofy=|x| by the factor12

Step 6. graph of the transformed function 

Plot the graph of the functiony=14|x| on the same Cartesian plane

graph of y=14|x| is equivalent to the vertically compressed graph ofy=|x| by the factor14

Step 7. graph of the transformed function 

Plot the graph of the functiony=5|x| on the same Cartesian plane

graph of y=5|x| is equivalent to the vertically stretched graph of y=|x| by the factor 5
