For what values of the variable does the following expression make sense: three times the square root of "a"

Using the domain concept, it is found that the expression makes sense for values of a that are of 0 or greater, than is,

The domain of a data-set is the set that contains all possible input values.

In this problem, the expression "three times the square root of a" is given by:

The square root function is valid for non-negative values, hence the domain of is , which are the values for which the expression makes sense.

This question revolves around the concept of domain (primarily) and range (secondarily).  The domain of the square root function is [0, +infinity).

The domain of "three times the sqrt of a" shares that domain:  [0, +infinity).

We were not asked to come up with the range, but if the range is wanted, it is

[0, +infinity).
