If (x + 8) is a factor of f(x), which of the following must be true?

Sedaia [141]

Answer:

f(-8) = 0

Step-by-step explanation:

If (x+8) is a factor of f(x), then for some expression p, we have ...

f(x) = (x+8)p

Evaluated at x=-8, this gives ...

f(-8) = (-8+8)p = 0p

f(-8) = 0 . . . . must be true

_____

Similarly, f(8) = (8+8)p = 16p. This may or may not be zero, depending on the factors of p. The only offered statement that <em>must</em> be true is the one shown above.
