Question

(f(x))/(x-5) produces a remainder of 8. Which is true?

A) f(5)=-8 B) f(5)=8
C) f(-5)=-8 D) f(-5)=8

Answer 1

B) f(5) = 8

Explanation:

Remainder Theorem

When a polynomial f(x) is divided by (x − c) the remainder is f(c).

Therefore, if f(x) is divided by (x - 5) the remainder is f(5).

As the remainder is 8, then f(5) = 8.
