A zero. Zero in the denominator make the expression undefined for algebraic purposes.
You do not. If you do, the expression is undefined: it has no value.
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
Yes, it is true.
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.
a value of zero in the denominator makes the fraction 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.
The answer depends on the part of the question that is missing.
If the denominator has a zero value.
a rational expression is undefined when the denominator is 0 because we cannot dvide by 0.
if there is 0 in the numerator it is zero regardless. But if it's zero in the denominator and zero in the numerator then it is undefined in all such cases where the denominator equals zero.
A rational number is any number that can be expressed as a fraction. It becomes meaningless or undefined when the lower number, the denominator, its 0 (zero)
A quotient in which the numerator or denominator are undefined will be undefined. For example p/q is an undefined quotient until you know something about p and q. Also, if the denominator is zero, the division is undefined.
If the denominator is 0 then the fraction is undefined.
a rational express ion undefined when the denominator is 0 because we cannot dvide by 0. For example, 9/x is undefine when x is 0 because we would be dividing by 0. Similarly 2/(7-x) is undefined for x=7 because we once again have a zero in the denominator. To find where a rational expression is undefined, set the denominator equal to 0 so if we have p/q where q is any number or expression, set and solve q=0 From, Doctor Huge Dick
when the denominator is zero example: 5/0
We set the denominator to zero to find the singularities: points where the graph is undefined.
One way is if the denominator becomes zero.
Undefined slope is a vertical line along the horizontal point of origin., the slope would have a denominator of zero, which is undefined.
A line with an undefined slope is a vertical line. A line with a slope of zero is a horizontal line. If you use the formula for slope m = (y2-y1) divided by (x2-x1)... For an undefined slope you will get zero in the denominator, which you cannot have because you cannot divide by zero. For a slope equal to zero, you will get a zero in the numerator. Zero divided by any non-zero denominator, will give you a slope of zero.
