Answer:
We conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
Step-by-step explanation:
If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
For example, let the function
It is clear that the given function becomes undefined at x = 3 in the denominator.
i.e. 3-3 = 0
It means, the function can not have x = 3, otherwise, the function will become undefined.
In other words, if the function has a vertical asymptote at x = 3, then the function is undefined at the value.
Therefore, we conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

Step-by-step explanation:
Factorise both denominators
x² + 2x = x(x + 2) ← common factor of x
x² - 4 = (x - 2)(x + 2) ← difference of squares
Before subtracting we require common denominators
Multiply the numerator/denominator of the first fraction by (x - 2)
Multiply the numerator of the second fraction by x
= -
Distribute and simplify the numerator leaving the denominator
=
=
