The domain of the function is {-5, 1, 3, 5}.
What is the domain of a function?
A function is an argument or a statement. The domain of a function is said to be a set of input values to an argument for which the function is defined.
The domain of a function can be represented in inequality notation, interval notation, set notation, or graphical notation.
From the given graph, we are to determine the domain of the function, since the domain is the set of the x-values, we will check the position of the points on the graph and locate the x-axis values at which the points are located.
Therefore, the domain of the function is {-5, 1, 3, 5}.
