I have
 to graph each relation
 decide if it is a function
 state the domain and the range.
1) {(2,3),(4,3),(5,1),(1,3)}
how would I decide if something is a function in general?
I kind of remember the domain and the range,but since I did this 2 years ago I forgot. Is the domain the x and the range the y?

I found out about domain and range
how would I solve this then:
y=line x3 line
y^2 = x
y = (x+1)/(x3)

for those how would I get the domain and range

for y = sqrt x
the domain is like R something?

You need to look up your notes and your textbooks to review the chapter(s) on functions, domain and range.
The graph is an arrow graph that relates each member of the domain to the corresponding member in the range.
The domain contains the xvalue of all the ordered pairs, and the range, the yvalues.
