Use Descartes' Rule of Signs to determine the possible number of positive and negative real zeros for the function. Then, use a graph to determine the actual number of positive and negative real zeros.P(x) = 3x6 - 8x4 - 4x3 + 7x2 - 7x
A. possible: 1 or 3 pos, 0 or 2 neg
actual: 1 pos, 0 neg (0 is also a zero)
B. possible: 1 or 3 pos, 0 or 2 neg
actual: 1 pos, 0 neg (0 is also a zero)
C. possible: 0 or 2 pos, 1 or 3 neg
actual: 0 pos, 1 neg (0 is also a zero)
D. possible: 0 or 2 pos, 1 or 3 neg
actual: 0 pos, 1 neg (0 is also a zero)
