• Relation t is not a function. The inverse of relation t is a function.

Answer 1

• Relation t is a function. The inverse of relation t is not a function.

This is because in order for an inverse to be a function, each element in the codomain must have exactly one corresponding element in the domain. In the given relation t, there are two elements in the codomain (4 and 8) that have multiple corresponding elements in the domain. Therefore, the inverse of relation t is not a function.
