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 function has vertical asymptotes at x-values for which it is and near which the function's values become very positive or negative numbers?

Undefined; large


Are the any values for x for which each rational expression is undefined xoverx plus 8?

The expression X/(X+8) is undefined at X=-8, because that would be division by zero.


What is called when the denominator is zero in a rational function?

The function is not defined at any values at which the denominator is zero.


What are limits in maths?

Limits (or limiting values) are values that a function may approach (but not actually reach) as the argument of the function approaches some given value. The function is usually not defined for that particular value of the argument.


What is a rational function?

In mathematics, a rational function is any function which can be written as the ratio of two polynomial functions. Neither the coefficients of the polynomials nor the values taken by the function are necessarily rational numbers.In the case of one variable, , a function is called a rational function if and only if it can be written in the formwhere and are polynomial functions in and is not the zero polynomial. The domain of is the set of all points for which the denominator is not zero, where one assumes that the fraction is written in its lower degree terms, that is, and have several factors of the positive degree.Every polynomial function is a rational function with . A function that cannot be written in this form (for example, ) is not a rational function (but the adjective "irrational" is not generally used for functions, but only for numbers).An expression of the form is called a rational expression. The need not be a variable. In abstract algebra the is called an indeterminate.A rational equation is an equation in which two rational expressions are set equal to each other. These expressions obey the same rules as fractions. The equations can be solved by cross-multiplying. Division by zero is undefined, so that a solution causing formal division by zero is rejected.


What is rational values?

Rational values- those are necessary to the functions and fulfillment of intellect and will.


What values of x make the expression 5-xx(x-2) undefined?

Which of these values of x make the expression undefined? 5-x/x(x-2)


If the square root of a rational number X was divided by another rational number Y and the result would be undefined what could be the possible values of X and Y?

probably x would be negative. This is because the square root of a negative number is not a real number (no real number squared can be negative). ory is 0. any number divided by 0 = infinity. and undefined is another way of saying infinity.

What is an undefined term?

An undefined term is usually applied to a function (or a part) where for some values of the operands the function is not defined within the field in which it is defined. It may be defined in a bigger field. For example, division by zero is not defined anywhere. Square roots of negative numbers are not defined in the domain of Real numbers, but they are perfectly OK in the Complex field.


What is the range of fx equals 2-3x?

The range is the all the possible y-values for the function. f(x)=2-3x does not have any points where it is undefined because it is a linear function ( a line). The answer is all real numbers or (-infinity,infinity)
