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.

c

step-by-step explanation:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
