If (X + 8) is a factor of f(x), which of the following must be true? Both - 8 and x 8 are roots of f(x).
O Neither x 8 nor x = 8 is a root of f(x)
f( -8) = 0
(8) = 0

C

Step-by-step explanation:

If (X + 8) is a factor of f(x), then to find the root, equate the factor to zero. That is,

X + 8 = 0

X = 0 - 8

X = -8

If -8 is substituted into f(x), the equation will tend to zero. That is,

F( -8 ) = 0

C is therefore the correct answer.
