# 12)Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial i

n standard form.

5, -3, and -1 + 3i

f(x) = x4 + 12.5x2 - 50x - 150

f(x) = x4 - 4x3 + 15x2 + 25x + 150

f(x) = x4 - 4x3 - 15x2 - 25x - 150

f(x) = x4 - 9x2 - 50x - 150
