Question

If (x - 5) is a factor of f(x), which of the following must be true?

O
O
O
Aroot of f(x) is x = -5.
A root of f(x) is x = 5.
Both x = -5 and x = 5 are roots of f(x).
Neither x = -5 nor x = 5 is a root of f(x).

Answer 1

B) A root of f(x) is x = 5

Explanation:

Answer 2

Answer: a root of f(x)= 5

Step-by-step explanation: they did not give you the equation so there is no way you can assume -5 is a root as well so when you take x-5 and set it equal to 0 you add five to both sides causing x to equal 5
