The domain of a function y=f(x) is the set of all real values in which x lies, provided f(x) is real.

The range is the value of y=f(x) when x takes on values in the domain.

For the given graph the domain is `[-4, 4]`

and the range is ` [0, 4]`

The domain of a function is the set of all possible input values (usually x), which allows the function formula to work.

Therefore, the domain is: `(-4, 4]`  

The range is the set of all possible output values (usually y), which result from using the function formula.

Therefore, the range is: `[0, 4]`
