If (x – 5) is a factor of f(x), which of the following must be true?
a root of f(x) is x = –5.
a root of f(x) is x = 5.
both x = –5 and x = 5 are roots of f(x).
neither x = –5 nor x = 5 is a root of f(x).

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
