What makes a rational expression 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
What values of x make the expression 5-xx(x-2) undefined?
Oh honey, let me break it down for you. The expression 5-xx(x-2) becomes undefined when x = 2. Why? Because when x = 2, you end up dividing by zero, and we all know you can't divide by zero in this math game. So, be sure to steer clear of x = 2 if you want to keep things running smoothly.
What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
If a function has a vertical asymptote at a certain x-value then the function is at that value?
Undefined

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 value of x makes the value of the expression equal to 2?
Since there is no expression given, there is no sensible answer.

What does excluded value mean?
An excluded value is any x value that makes a function value y undefined. For a rational function, an excluded value is a value that makes the denominator equal to 0.
How do you write a rational expression that is undefined when x equals 4 and x equals 0?
One possible expression is [ 1/(x - 4)+ 1/x ].
What is a fraction that is 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.
How do you find T8 sec x cos x?
If cos(x) = 0 then the expression is undefined. Otherwise, it is T8.
How do you solve for an undefined slope?
An undefined slope will always be a vertical line through any point of choice where the value of x = 0; while the y value changes indefinitely, the value of x will always equal zero, and therefore is undefined.

For which value of x is the expression x-4 over x plus 3 undefined?
The way for a fraction to be undefined is to have the lower number to be zero. So you only look at the bottom of the fraction and find what it would take to make it equal to zero. x+3=0 You would have to subtract three from both sides and you would get x= -3. So the answer is -3.
