Find the root and standard form of the polynomial function with the given roots and y-intercept.Roots: 5 and -2; f(0) = 50
A. f(x) = 5(x - 5)(x + 2); f(x) = 5x2 + 15x + 50
B. f(x) = (x - 5)(x + 2); f(x) = x2 - 15x + 50
C. f(x) = -5(x + 5)(x - 2); f(x) = -5x2 - 15x - 50
D. f(x) = -5(x - 5)(x + 2); f(x) = -5x2 + 15x + 50
