Graphing Ration Functions:

-To graph a rational function, you find the asymptotes and the intercepts

Example:

X-intercept: (set the numerator equal to 0) 2x=0; 0

Y-intercept: ( plug 0 in for x in the equation) 0

Vertical asymptote: (Denominator) Horizontal asymptote: (exponents)

y=0

(x+2)(x-1)

x=-2, x=1

-To find out which way the line goes, plug in an x value thats appropriate for you asymptote and that will tell you if its positive or negative

-On Occasion there can be a hole, which means there is a multiplicity
