Find the domain and range of the function. (enter your answers using interval notation.) h(x) = √4 − x^2

The range and domain of this function is [-2, 2]

Step-by-step explanation:

For the domain it must be fulfilled that . Then, . This expression is true for the values of that make the factors simultaneously non-negative or non-positive.

Case non-negative factors

implies that , that is

implies that , that is, . The intersection of the previous sets is [-2, 2].

Case non positive factors

implies that , that is

implies that , that is, . The intersection of the previous sets is empty.

Then the domain of the function is [-2, 2]

The range of this function is the domain of its inverse. The inverse of the function is itself, so the range is [-2, 2]
