5. Does this table represent a function? Explain using what you know about functions

Day of week output

Sunday 3, 2

Monday 2

Tuesday 1, 2

Wednesday 4

Thursday 2

Friday 3, 3

Saturday 1

No, this table does not represent a function. In a function, each input (in this case, the day of the week) must have exactly one output. However, in this table, some days of the week have multiple outputs. For example, Sunday has the outputs 3 and 2. Additionally, some days of the week have no outputs, which also violates the definition of a function.
