What is a rational algebraic expression?
A rational number is any number that can be written in the form a/b, where a and b are integers and b ≠0. it is necessary to exclude 0 because the fraction represents a ÷ b, and division by zero is undefined.A rational expression is an expression that can be written in the form P/Q where P and Q are polynomials and the value of Q is not zero.Some examples of rational expressions:-5/3; (x^2 + 1)/2; 7/(y -1); (ab)/c; [(a^2)(b]/c^2; (z^2 + 3z + 2)/ (z + 1) ect.Like a rational number, a rational expression represents a division, and so the denominator cannot be 0. A rational expression is undefined for any value of the variable that makes the denominator equal to 0. So we say that the domain for a rational expression is all real numbers except those that make the denominator equal to 0.Examples:1) x/2Since the denominator is 2, which is a constant, the expression is defined for all real number values of x.2) 2/xSince the denominator x is a variable, the expression is undefined when x = 03) 2/(x - 1)x - 1 ≠0x ≠1The domain is {x| x ≠1}. Or you can say:The expression is undefined when x = 1.4) 2/(x^2 + 1)Since the denominator never will equal to 0, the domain is all real number values of x.

What value of x makes the expression x undefined?
+1/0 or -1/0 or 0/0
What is the value of the rational expression below when x is equal to 3?
4
For what value of x is the rational expression below equal to zero?
2
What is the value of the rational expression below when xis equal to 3?
This is wrong
If a function has a vertical asymptote at a certain x-value then the function is at that value?
Undefined
How do you set the denominator equal to zero?
You do not. If you do, the expression is undefined: it has no value.
Is a rational number is a rational expression?
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
What statement best describes the excluded values of a rational expression?
The excluded values of a rational expression are the values of the variable that make the denominator equal to zero. These values are not in the domain of the expression, as division by zero is undefined. To identify excluded values, set the denominator equal to zero and solve for the variable. Any solution to this equation represents an excluded value.

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.
