A polynomial function has roots –5 and 1. Which of the following could represent this function?

f(x) = (x + 5)(x + 1)

f(x) = (x – 5)(x – 1)

f(x) = (x – 5)(x + 1)

f(x) = (x + 5)(x – 1)

The corresponding polynomial function is

f(x) = x2 + 5x - 1

f(x) = x2 + 4x - 5

f(x) = x2 + 5x - 5

f(x) = x2 - 4x - 5

The polynomial function of least degree with a leading coefficient of 1 is:f(x) = x3 + Ax2 + Bx + CA =
