Which second degree polynomial function has a leading coefficient of 2 and roots –3 and 5?
a.) f(x) = 2x2 + 4x – 30
b.) f(x) = 2x2 + 2x – 15
c.) f(x) = 2x2 – 4x – 30
d.) f(x) = 2x2 – 2x – 15

From these given details result f(x)=2(x+3)(x-5) so

f(x)= 2(x^2 -5x +3x -15)

f(x)= 2(x^2 -2x -15)

f(X)= 2x^2 -4x -30  so the 3rd choice is right sure

C. f(x) = 2x2 – 4x – 30
