Answer:
The domain can either be discrete or continuous. A discrete function would have x-values that stand alone, but not have an interval around them. For example the number of children you have will be 0, 1, 2, 3, and so on, but nothing in between 1 and 2. A continuous function will have all values of x in an interval
help me by marking as brainliest....
A discrete function is a function in which the domain and range are each a discrete set of values, rather than an interval in . Recall from a prior lesson that an interval includes all values between the specified minimum and maximum.Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
