XINTERCEPTS: Where the graph crosses the xaxis.
Hey, this is the same as finding the zeros!
Set 

and solve 
But, here's the cool thing:
For these
rational guys, you just need to set the numerator
= 0
and solve!
Why? That's a great question  I'm glad you asked...
Well, when a fraction is 0, it's the same as saying the numerator is 0:
So, set the numerator = 0 and solve.
Check it out:


So, the xintercepts are the points

Find the xintercepts of 
BIG NOTE:
These processes find the ONLY
intercepts!
