Suppose f(x) is a rational function with leading term -1, has three roots: a root at z = -2 of degree 1, a root at r = 0 of degree 1, and a root at r= 1 of degree 1, f(x) also has a vertical asymptote at r= -1 of degree 3.1) leading term: -12) roots : ? 2 (deg. 4), 0 (deg. 1), 1 ( deg.1)(a) Determine the sign decomposition of f(x):
