What do we call the set of all possible outputs of a function?

  1. Domain

  2. Range

  3. Input Values

  4. Independent Variables

The correct answer is: Range

The set of all possible outputs of a function is known as the range. When a function is defined, it takes input values from a specific set (the domain) and transforms them into corresponding output values. The range consists of all the values that the function can produce from the given inputs. In a practical sense, if you have a function that defines how to calculate outputs based on certain inputs, the range provides a complete picture of the results that can be obtained. For example, if you have a function that calculates the area of a circle based on its radius, the range includes all the possible area values that can be generated from valid radius inputs. This distinction is important in understanding the behavior of functions and their corresponding graphs, where the range indicates the vertical spread of points on the graph.
