Josh graphs a system of equations to determine the roots of the polynomial equation . From the graph, he determines that there are two solutions to the equation. Which statement is true? He is correct because the graph shows two intersection points. He is correct because the least exponent of the system is two so there must be two solutions. He is not correct because the greatest exponent of the system is five so there must be five solutions, three of which must be multiplicities or complex. He is not correct because the difference of the exponents is three, so there must be three solutions, one of which is a multiplicity.

c. He is not correct because the greatest exponent of the system is five so there must be five solutions, three of which must be multiplicities or complex.
