What about rational functions creates undefined and asymptotic behavior?

A rational function is the ratio of two polynomial functions. The function that is the denominator will have roots (or zeros) in the complex field and may have real roots. If it has real roots, then evaluating the rational function at such points will require division by zero. This is not defined.
Since polynomials are continuous functions, their value will be close to zero near their roots. So, near a zero, the rational function will entail division by a very small quantity and this will result in the asymptotic behaviour.

Why 5 divided by 0 undefined?

Why are rational functions called rational functions?
Because they are represented as fractions.
Is the square root of three fifths irrational rational or undefined?
Irrational
Is 23 divided by 0 a rational number?
Undefined: You cannot divide by zero
Is it true that a rational expression is undefined whenever it's denominator is zero?
Yes, it is true.
What rational functions will have a hole at x2?
A rational function is undefined - you might say that it "has a hole" - at any point where the denominator is zero. Assuming you mean "... hole at x = 2", any rational function which has the factor (x-2) in its denominator will have a hole at x = 2.
When the denominator is zero in a rational function what is that called?
Undefined.
When is a racional expression undefined?
a rational expression is undefined when the denominator is 0 because we cannot dvide by 0.

Is zero always or sometimes a rational number?
Zero by definition is always a rational number. It can sometimes be the cause of mathematical concepts being undefined. For example, a number can not be divided by zero. Dividing by zero is undefined.
