Can a degree 3 polynomial intersect a degree 4 polynomial in exactly five points? Explain. Solution Let, f(x) be degree 3 polynomial ANd g(x) be degree 4 polynoimal So points of intersection are given by roots of the polynomial h(x)=g(x)-f(x) But, h(x) is degree 4 polynoimal and hence has atmost 4 roots So there can be atmost 4 points of intersection.
