I have the graph of a function, as shown in the above link. Pretend you just see the graph and dont know the function the graph represents. 

 

I have 4 choices of functions that can match the graph:

 A. y=(2x^3)/x^2+5)

B. y=(3x^2)/(2x-1)

C. y=(x^3)/(2x^2-2)

D. y=(x^2)/(3x+4)

 

I have to match the function with the graph but how do I show work for this?? 

 

thanks.

Identify where the singularities are (i.e. the places where the denominator goes to zero.
