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)

Which polynomial function has a root of 1 with multiplicity 2 and a root of 6 with multiplicity 1?

f(x) = (x – 1)(x – 6)

f(x) = 2(x – 1)(x – 6)

f(x) = (x – 1)(x – 1)(x – 6)

f(x) = (x – 1)(x – 6)(x – 6)
