Question

lf (x + k) is a factor of f(x), which of the following must be true? F(k)=0 f(-k)=0 a root of f(k) is x=k a y intercept of f(k) is x=-k

Answer 1

Answer:

a root of f(k) is x=k

Step-by-step explanation:

(x + k) is a factor of f(x)

This means that:

$x + k = 0$

$x = -k$

Thus, one root of f(x) is x = -k, and the correct answer is given by the third option, from top to bottom.
