No. A value that is unknown may not be a variable but simply a constant whose value needs to be calculated.
If the value of a function cannot be determined for any value of the independent variable, then, the value the function seems to be approaching would be its limiting value for that particular value of the independent variable.
any letter can be a variable
it is the variable that is changed by the manipulated variable, which is to purposely change a variable to see if it has any affect. the part that has effect is the responding variable

A variable is used purely for the purpose of storing a single value. Being variable, the value can be changed at any time. A constant is the opposite of a variable; its value cannot be changed.
A variable is any named value of a specified type that can hold any value of that type, and that can change that value at any time while the name is in scope. A constant is exactly the same as a variable except that its value must be set at the point of instantiation and the given value cannot be altered while the name remains in scope. In other words, a variable is a value that may vary while a constant is a value that always remains the same.
If the value of a function cannot be determined for any value of the independent variable, then, the value the function seems to be approaching would be its limiting value for that particular value of the independent variable.
you can change the value of x to any new value and it has no effect on the value of y.
Simply reassign the value. If you have a variable $x, and you add 1 to it, you can store the value by stating $x = $x+1;
True.
A private variable is one that is accessible only to the current class and cannot be accessed by any other class, including the ones that extend from it. A final variable is one that cannot be modified once it is initialized and assigned a value.
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
Temperature change is a continuous and interval variable, meaning it can take any real value within a certain range and the differences between values are consistent.
