How do I find out if this equation is a function or not?

The question is 
Determine if each relation is or is not a function.
And the questions are
1. y=2x2-3x+1
2. y=3/2x-4
3. y=-3x4+x3-2x+1
I would like to know the explainations. From the content of the workbook, I am guessing that somehow I need to find out if there are more than one domain using those equations.
If you know how to do these problems and can help, it would be great!
Thank you!
