Would f(x) = (x^2+2x+3)/3 be considered a rational function? I'm not quite sure what the guidelines are with classifying the various types of functions.

No....a rational function is one that has a polynomial in the numerator and the denominator....note that

 

(x + 3)  / (x^2 - 2)    would be an example....but...

 

 (x^2+2x+3)/3  is actually just

 

(1/3)x^2  + (2/3)x  +  1       and this is just a quadratic function.....
