Answer:

Option 3

Step-by-step explanation:

(f/g)(x) = f(x)/g(x)

Since g(x) is in the denominator, it can't be 0.

(Functions is undefined when the denominator = 0)

This fraction becomes undefined when:

-14x² - 1 = 0

14x² = -1

x² = -1/14

So x² should not be -1/14

Answer:

The answer is 3rd point.

Step-by-step explanation:

As you already know how to find (f/g)(x). By looking at the last part of each expression, you can find out the answer :

x² = -1/14

x = √(-1/14) (rej)

You can let any value equals to x² but not a negative value. Beacuse you cannot square root a negative value, it will gives you a MATHS ERROR.
