For a function defined by y = f(x), the set of values in which x lies is called the domain and the set of values in which y lies is called the range.

From the graph of the function that is given it is seen that the domain consists of the set [2, 5] and the range consists of the set [-2, 2]

The domain of the given function is [2, 5] and the range is [-2, 2]
