If 4 is a root of f(x), which of the following is a factor of f(x)? (x+4)
neither (x+4) nor (x-4)
(x-4)
(x+4) and (x-4)

Given:

4 is a root of f(x).

To find:

A factor of f(x).

Solution:

We know that, if c is a root of a function f(x), then (x-c) is a factor of f(x).

In the given problem, 4 is a root of f(x).

So, we have c=4.

By using the above property we can say that, (x-4) is a factor of function f(x).

Since, (x-4) is a factor of function f(x), therefore, the correct option is C.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

lol   i know im kinda tired too
