What can't you have in the denominator?
A zero. Zero in the denominator make the expression undefined for algebraic purposes.
How do you set the denominator equal to zero?
You do not. If you do, the expression is undefined: it has no value.
Is it true that a rational expression is undefined whenever it's denominator is zero?
Yes, it is true.
Why is the denominator set to zero to graph a rational expression?
When the denominator is equal to zero, the expression is undefined. Close to those places, the expression tends towards plus infinity, or minus infinity. In other words, setting the denominator to zero will tell you where there are vertical asymptotes.
If a fraction in the denominator it is undefined IT HAS WHAT its denominate?
a value of zero in the denominator makes the fraction undefined
What can't you have in the denominator?

A rational expression is undefined whenever its denominator is zero-?
True
How do you set the denominator equal to zero?
You do not. If you do, the expression is undefined: it has no value.
How do you determine the values for which a rational expression is undefined?
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
A rational expression is undefined whenever its denominator is zero?
False

What is a fraction that is undefined?
A fraction such that the divisor (denominator) is zero is undefined. Such a division is expressed as x/0 where x is the dividend (numerator). In ordinary arithmetic, the expression has no meaning so division by zero is undefined.
If a fraction in the denominator it is undefined IT HAS WHAT its denominate?
a value of zero in the denominator makes the fraction undefined
If a fraction has - in the denominator it is undefined?
The answer depends on the part of the question that is missing.
What value of n makes the expression n plus 4 over n-3 undefined?
1
If a fraction in the denominator it is undefined IT HAS WHAT?
If the denominator has a zero value.
