The domain of a function consists of all the possible input values (often represented as ‘x’) that can be used in the function without causing any issues like division by zero or taking the square root of a negative number.
In this case, the values provided are: 3, 6, 0, 2, 4, 7, 11, and 15. If these numbers are the only ones considered for inputs into a function, then the domain of the function includes all these values.
To represent this set, we can write it in the following way: {0, 2, 3, 4, 6, 7, 11, 15}. This set includes each unique value without repetition, and it clearly defines the input values the function can accept.
