To determine if the pair (7, 2.4) represents a function, we need to clarify how we are interpreting this.
A function is a relation in which each input (or x-value) is associated with exactly one output (or y-value). In this case, if we consider 7 as the input and 2.4 as the output, then yes, (7, 2.4) can be seen as a function because the single input 7 corresponds to a single output 2.4.
If you are referring to this in the context of a set of ordered pairs, then a set containing just this point, such as {(7, 2.4)}, is indeed a function because there are no two different outputs for the same input.
If you have more pairs and want to check if they form a function, you would need to make sure that no input is repeated with a different output.
