13. Write the polynomial function of least degree that has zeros of x = -1 and x = 5 a. f(x) = x2 - 4x - 5 b. f(x) =x'+x2 - 5x -5 c. f(x) =x3+x2+25x+25 d. f(x) = x2 + 6x -15 14. Write the polynomial function of least degree that has zeros of x - 3 with a multiplicity of 2, x = ~2, and x =- ~2 a. g(x) = x4 - 6x' +7x2+ 12x-18 b. g(x) = x*-5x' + 4x2 + 10x-12 c. g(x) = x' - 3x2 -2x +6 d. g(x) = x2 - 3x - 3~/2 -x~2 15. Write the polynomial function of least degree that has zeros of x = -i and x = 1. (assume all coefficients must be real) X - a. x' + 2x - 1 b. x'+x+x-2 C. X -x'+x-1 d. x' - x - 12-x
