Question 3 and 4

If you can answer and provide a reason for your answer choice.

Answer 1

Table on the left is a function

Table on the right is NOT a function

Explanation:

Table on the left: we can see that for different elements/values in the Domain there is a single corresponding value in the range. Then it satisfies the condition for a function.

Table on the right: we notice that for the same element in the Domain (-6) there are three different corresponding values in the Range. Something similar occurs for the element "1" (there are two different elements in the Range this value connects to). This doesn't satisfy the conditions for this relationship to be a function where each element in the Domain should connect to only one element in the Range.
