What is a parent function?

• A function that is not shifted up, down, left, or right

• A function that can be graphed

• The function that has kids

• The simplest equation of a type (identified by it's mathematical operator)

How do you shift a function up or down?

• By moving it

• By adding or subtracting a number outside of the operator

• I can't drive a stick shift

• By adding or subtracting a number inside the operator with x

How do you shift a function left of right?

• By moving it

• By adding or subtracting a number outside of the operator

• I can't drive a stick shift

• By adding or subtracting a number inside the operator with x

How do you change the slope or curve of a parent function?

• By moving it

• By adding or subtracting a number outside of the operator

• With a multiplier

• By adding or subtracting a number inside the operator with x
