## Expert Answers The domain is all the values that x is allowed to take on. The range is all values that y is allowed to take on.

Therefore, the domain is: `[-4, 4)`

The range is:  `{-4, -2, 0, 2}`

Approved by eNotes Editorial Team The domain of a function y = f(x) is the set in which x lies for which f(x) is real. The range is the value of y = f(x) when x takes on values in the domain.

From the graph of the function, it takes on values of x that lie in [-4, 4). This is the domain. The range of the function is {-4, -2, 0, 2}

The domain from the given graph is [-4, 4) and the range is {-4, -2, 0, 2}
