Step-by-step explanation
Polynomial functions are those functions that consist of one or more variables and constants. Depending on the degree of the polynomial, it has a certain number of zeroes.
Hence in the case of a three degree polynomial, the number of real zeros is either less than or equal to three, but never more than three. Therefore, in the given question since it is impossible for the polynomial to have 5 real zeros and 4 turning points.
