Find the factored form of a polynomial function f whose roots are given. Then find values of the leading coefficient for which the coefficients of f in standard form are integers.Roots: 
, 
, -3
A. f(x) = 75a(5x + 1)(15x + 1)(x - 3)
a = k, for any integer k
B. f(x) = 
(5x - 1)(15x - 1)(x + 3)
a = 75k, for any integer k
C. f(x) = 75a(5x - 1)(15x - 1)(x + 3)
a = 75k, for any integer k
D. f(x) = 
(5x + 1)(15x + 1)(x - 3)
a = 75k, for any integer k
