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.
What do the asymptotes represent when you graph the tangent function?
When you graph a tangent function, the asymptotes represent x values 90 and 270.
How many non-verticle asymptotes can a rational function have?
Not sure what non-verticle means, but a rational function can have up to 2 non-vertical asymptotes,
Why is it not possible for the graph of a rational function to cross its vertical asymptotes?
A vertical asymptote represents a value of the independent variable where the function approaches infinity or negative infinity, indicating that the function is undefined at that point. Since rational functions are defined as the ratio of two polynomials, if the denominator equals zero (which occurs at the vertical asymptote), the function cannot take on a finite value or cross that line. Therefore, the graph of a rational function cannot intersect its vertical asymptotes.
What is the equation of the asymptote of the graph of?
To determine the equation of the asymptote of a graph, you typically need to analyze the function's behavior as it approaches certain values (often infinity) or points of discontinuity. For rational functions, vertical asymptotes occur where the denominator equals zero, while horizontal asymptotes can be found by comparing the degrees of the numerator and denominator. If you provide a specific function, I can give you its asymptote equations.

What are the equation of the asymptotes for each graph?
that's simple an equation is settled of asymptotes so if you know the asymptotes... etc etc Need more help? write it
Can the graph of a rational function have more than one vertical asymptote?
Assume the rational function is in its simplest form (if not, simplify it). If the denominator is a quadratic or of a higher power then it can have more than one roots and each one of these roots will result in a vertical asymptote. So, the graph of a rational function will have as many vertical asymptotes as there are distinct roots in its denominator.

For rational functions, vertical asymptotes occur where the denominator equals zero, while horizontal asymptotes can be found by comparing the degrees of the numerator and denominator. If you provide a specific function, I can give you its asymptote equations.
Can a rational function have no vertical horizontal oblique asymptotes?
No, it will always have one.
Why are asymptotes important characteristics of rational functions?
Asymptotes are one way - not the only way, but one of several - to analyze the general behavior of a function.
What happens in the graphs of the functions that have variables in the denominator?
The answer depends on the form of the expression in the denominator. For example, the graph os 1/(1 + x2) has a pretty well-behaved graph, with a maximum vaue of 1 when x = 0 and asymptotes of y = 0
What does a rational function look like?
A rational function is a function defined as the ratio of two polynomial functions, typically expressed in the form ( f(x) = \frac{P(x)}{Q(x)} ), where ( P(x) ) and ( Q(x) ) are polynomials. The graph of a rational function can exhibit a variety of behaviors, including vertical and horizontal asymptotes, and can have holes where the function is undefined. The degree of the polynomials affects the function's end behavior and the locations of its asymptotes. Overall, rational functions can represent complex relationships and are often used in calculus and algebra.
