Using synthetic division, determine whether the numbers are zeros of the polynomial function. -5, 3; f(x) = 3x²+10x²-19x+30 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The number - 5 is a zero of the polynomial function because f(-5)= | the polynomial function because f(3) = ☐ OB. Neither - 5 nor 3 is a zero of the polynomial function because f(-5)= | ○ C. The number - 5 is not a zero of the polynomial function because f( -5)= the polynomial function because f(3) =| and the number 3 is not a zero of and f(3)= and the number 3 is a zero of ○ D. Both - 5 and 3 are zeros of the polynomial function because f( -5)=0 and f(3) = 0.
