     The function h(x) is given in the following graph.  What is the limit as x goes to infinity?  What is the limit as x goes to 3? 
  
  Solution
We can see as x goes to infinity the graph tends to 4
a. So limit as x goes to infintiy =4
b.
As we approach x=3 from teh right limit is infinity
If we approach x=3 from the left the limit is -infinity
So the limit at x=3 is not defined
