A function is only considered undefined if you divide by 0. An exception to this rule would be if the numerator is also 0. Then it is considered in an
The best way to approach this would be to factor everything and see if we can simplify.
The numerator is 0 when s =0 or s is
The denominator is 0 when s = -8 or 8.
All we care about at this point is the denominator since division by 0 gives us an undefined form. It is always good to check that the number doesn't give you a
form... that is why we checked the numerator as well. Good habit.
In this case it doesn't.
So our answers are
