http://www.freemathvideos.com In this math tutorial I show you how to find the left and right hand behavior by using the leading coefficient and degree of the polynomial. If the degree is even of the leading coefficient then the end behavior is either both positive or both negative depending on the sign of the leading coefficient. If the degree is odd for the leading coefficient the the end behavior is either positive to negative or negative to positive depending on the sign of the leading coefficient.
f(x) = -x^2 + 6x + 9
