In Exercises 130–133, write the equation of a rational function f(x) = p(x)/q(x) having the indicated properties, in which the degrees of p and q are as small as possible. More than one correct function may be possible. Graph your function using a graphing utility to verify that it has the required properties.

f has a vertical asymptote given by x = 1, a slant asymptote whose equation is y = x, y-intercept at 2, and x-intercepts at -1 and 2.
