Any expression that contains one or more variable, such as x; x+2; x+y; x2, etc. Depending on the values of the variables, the expression can also have different values.
8
The assertion is not true. Consider the function f(x) =|x - 3|, which is the distance of x from the point 3. The function is defined for all x but the absolute value is required.
X2 Is an algebraic expression. X2 = 4 Is an equation that can be solved for X. The variable, X, in this case, has two values. In the expression any value can be substituted for X.
first, you have to divide. Then, you have to add X to what you got when you divided. After that, you shove it up your butt and cry
tan(-x) = -tan(x)
Which of these values of x make the expression undefined? 5-x/x(x-2)

Yes, as there are no other values in the expression.

The expression X/(X+8) is undefined at X=-8, because that would be division by zero.
-22x-8
It is an algebraic expression whose value depends on the values of y and x.
