Question

HOw to graph general rational functions?
like y=2x/x^2-1

Answer 1

step 1 :Set the denominator equal to zero and solve for x. Those values are your vertical asymptotes since x cannot equal zero.
step 2:Then plug in values to the left and right of the values you found in step two

Answer 2
