Writing Assignment:
You are the radical function
, you must explain to your teacher
be translated. Be sure to tell your teacher,
how you can
, what happens when:
 a number h is added under your radical such as
 a number k is added outside of your radical such as
 a number a is multiplied by your radical such as
 combine all three operations and explain what would happen to
You don’t want
, your teacher, to move you to the wrong place so be sure that you are
specific and use examples…you don’t want
to get confused or lost!
