1.  Solve the equation for x.

| x - 5| = 3 - 2x

 

2.  Given the functions : f(x) =  and g(x) = x-3

Find and simplify:

h(x) = (f + g) (x)          

j(x) = f (g (x))  

 

3. Find the following limit by hand. You can use graphing to help you get a sense for what the limit is.

 

 

4. Find the following limit by hand. You can use graphing to help you get a sense for what the limit is.

 

5. Find the natural domain of the function

 

6. Imagine a function f which is  defined on interval [0,3)U(3,),  has a right hand  limit at 1 equal to 0, has a left hand limit at 1 equal to 3,   is not defined at 3, has a left hand  limit at 3 equal to 2,  and has  no right  hand real limit at 3. Sketch the graph of your function.
