transformation question

Question

Describe the transformation that has taken place for the parent function f(x)=|x|

 

f(x)=5|x+7|

Answer 1

Linette,

 

There are two transformations involved, in this order:

 

1) Shift the graph of f(x) to the left 7 units.

2) Vertically stretch the graph by a factor of 5.

 

You can actually use these in either order for this function, but this doesn't hold true for every function, so please be careful.
