Question: In Problems 2132, determine the maximum number of real zeros that each polynomial function may have. Then use Descartes Rule of Signs to determine how

In Problems 21–32, determine the maximum number of real zeros that each polynomial function may have. Then use Descartes’ Rule of Signs to determine how many positive and how many negative real zeros each polynomial function may have. Do not attempt to find the zeros.


f(x) = -2x + 5x - x - 7 +5r
