F(x) = |2x + 1| + |x| − x vertical asymptotes

To find the vertical asymptote(s) of a rational function, simply set the denominator equal to 0 and solve for x. We mus set the denominator equal to 0 and solve: This quadratic can most easily be solved by factoring the trinomial and setting the factors equal to 0. There are vertical asymptotes at .
