Explanation:
if to graph the function B (see the attached picture), then
1) the smallest y-intercept - B;
2) the greatest x-intercept - B;
3) on the B decreasing - A is increasing;
4) negative intervals for the both functions - A: x∈(-6.5;-1.5); B: x∈(-∞;0)∩(0;+∞);
5) when x=-3 - the function B (-3) is greater than A (-5).
