Which second degree polynomial function has a leading coefficient of 2 and roots negative 3 and 5 ?

A quadratic with roots −3 and 5 has factors (x + 3)(x − 5). To make the leading coefficient 2, multiply by 2: 2(x + 3)(x − 5) = 2x² − 4x − 30. Therefore, the function is choice A, f(x) = 2x² − 4x − 30.
