Step-by-step explanation:
Which statements are true about the polynomial function?
f(x)=x4+5x3−x2−5x
Select each correct answer.
f(5)=0
f(x)=0
when x=−5
f(x)
divided by (x+5)
has a remainder of 0.
(x−5)
is a factor of f(x) .
When x=-5, f(x) IS 0.
f(x) divided by (x+5) has a remainder of 0. (x+5) is a factor of f(x).
But x-5 is NOT a factor of x
