What is range in IB maths?

In the context of the IB Maths course, the term range refers to the set of all possible output values of a function.

When considering a function, the range is the collection of y-values that the function can produce as outputs, based on the input values from its domain.

When discussing the range, you can use inequalities to express the set of values precisely.
