Generally, a numerical value is assigned in equations with variables or in mathematical expressions that include variables.
The assignment involves changing the variables in a mathematical expression or equation to specific numerical values.
For example
Answer:
By assigning the numerical value, the general form becomes a particular case.

Given the following function:
Does the function have a domain? If so, what is it?
Since the function's denominator equals 4, the domain of the function is all real numbers, meaning all X.
No, the entire domain
Given the following function:
Does the function have a domain? If so, what is it?
Since the denominator is positive for all X, the domain of the function is the entire domain.
That is, all X, therefore there is no domain restriction.
No, the entire domain
