A) Not a function
Step-by-step explanationA function is a relation which describes that there should be only one output for each input
Step 1
let's check the given ordered pair
![\begin{gathered} (x,y),\text{ x is the input, y is the output} \\ (-6,5)\text{ , -6}\Rightarrow5 \\ (-3,-7),\text{ -3}\Rightarrow-7 \\ (4,6),\text{ 4}\Rightarrow6 \\ (4,8).\text{ 4}\Rightarrow8 \end{gathered}]()
we can see that
the input 4 has 2 outputs 6 and 8, so
this is not a function, hence the answer is
A) Not a function
