What is the domain of the following function

The domain of the given function is equal to: {-4, 2, 6, 9}.What is a domain?In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values or numbers to a function and the domain of a graph comprises all the input numerical values which are shown on the x-axis.Generally speaking, the horizontal extent of the graph of a function represents all domain values and they are read and written from the smallest to the largest numerical values, and from the left of a graph to the right.By critically observing the given function, we can reasonably and logically deduce the following:Domain = {-4, 2, 6, 9}.Range = (-3, 1).Read more on domain here: brainly.com/question/17003159#SPJ1
