Notes on Board
y=kx: linear function; direct variations
y=k/x: reciprocal function; inverse variations

domain: what X must be to make the function undefined (make the denomenator 0)

Horizontal Asymptotes
1.) biggest power of X on bottom means HA: y=0
2.) powers are the same in numerator and denomenator means look at the leading coefficients of the highest powers of X, because they are the HA's
3.) biggest power of X on top means no HA
