Answer:
Domain of a function as the possible values of x.
Step-by-step explanation:
When we define a function, we state to types of variable, the dependent variable and the independent variable.
If we have a function of the form , here, x is the independent variable and y is the dependent variable, that is, y depends on x.
We define domain of a function as the possible values of x that is the independent variable. Thus, it is a set of all possible values of x such that the value of function f(x) or the value of y is defined.
To find the domain of a function, we should try to find all possible values x can take such that y is defined.
Example: In a function consisting of fraction we should choose the domain in such a manner that the denominator is not zero.
