Question

Identify the zeros of the given polynomial function and state their multiplicities. Describe also how the graph behaves with the x-axis.f(x) = $$x^{3}$$ + $$8x^{2} - 9x - 72$$

Accepted Answer

x = -3 has multiplicity 1; x = 3 has multiplicity 1; x = -8 has multiplicity 1; The graph crosses the x-axis at -3, 3, and -8

Answer

x = -3 has multiplicity 1; x = 3 has multiplicity 1; x = -8 has multiplicity 1; The graph touches the x-axis and turns around at -3, 3, and -8

Answer

x = -3 has multiplicity 2; The graph touches the x-axis and turns around at -3; x = 3 has multiplicity 1; The graph crosses the x-axis at 3

Answer

x = -8 has multiplicity 2; The graph touches the x-axis and turns around at -8; x = 3 has multiplicity 1; The graph crosses the x-axis at 3
