Target 7.1 I can perform the four operations on functions, and function composition

Use the following functions: ( ) 14 −= xxf , ( ) 32 −= xxg and ( ) 5+= xxh to find the following

1. ( )( )xhg + 2. ( )( )xhf − 3. ( )( )xgf

4. ( )( )xhg � 5. ( )( )xgh � 6. ( )( )3hf �

Target 7.2 I can find inverse functions including those functions with restricted domains (F.BF.4) (F.BF.4c) (F.BF.4d)

Determine if the functions are inverses of each other. Show work to verify.

Target 7.3 I can graph as well as identify and interpret characteristics of a radical function, including domain and

transformations. (F.IF.4) (F.IF.5) (F.BF.3) (F.IF.7b)

12. The period of a pendulum, the time it takes to complete one swing, is given by the formula P = 2� where L is the length in

meters of the pendulum and g is the acceleration due to gravity, 9.8 m/s�. To the nearest tenth, find the length of a pendulum that has a period of 3 seconds.

Target 7.4, 7.5, 7.6 I can rewrite expressions involving radicals and rational exponents using the properties of exponents. (N.RN.2) (N.RN.1)

Simplify. Assume all variables are non-negative.
