What is the rule of rational function?

What is the rule of rational function?

A rational function is defined as the quotient of polynomials in which the denominator has a degree of at least 1 . In other words, there must be a variable in the denominator. The general form of a rational function is p(x)q(x) , where p(x) and q(x) are polynomials and q(x)?0 .

How do you find a rational equation?

When we have an equation where the variable is in the denominator of a quotient, that?s a rational equation. We can solve it by multiplying both sides by the denominator, but we have to look out for extraneous solutions in the process.

What is a rational function example?

How to determine if a rational function is ever zero?

In other words, to determine if a rational function is ever zero all that we need to do is set the numerator equal to zero and solve. Once we have these solutions we just need to check that none of them make the denominator zero as well. In our case the numerator is one and will never be zero and so this function will have no x x -intercepts.

How to find the hole of a rational function?

If there is a common factor at both numerator and denominator, there is a hole for the rational function. Let (x ? a) be the common factor found at both numerator and denominator. Now we have to make (x ? a) equal to zero. So, there is a hole at x = a.

How to find the domain of a rational function?

A reciprocal function cannot have values in its domain that cause the denominator to equal zero. In general, to find the domain of a rational function, we need to determine which inputs would cause division by zero. The domain of a rational function includes all real numbers except those that cause the denominator to equal zero.

How to find the limit of a rational function?

From here, we can simply divide out of the fraction. We do not have to worry about being equal to 0, since in the context of this limit, the expression can be treated as if x will never equal 2. This gives us . The expression inside the limit is now linear, so the limit can be found by direct substitution. This obtains .
