An inverse function reverses the roles of inputs and outputs (of x-values and y-values).
If (2,4) is on the graph of a function, then (4,2) is on the graph of the inverse function.
If (9,7) is on the graph of the inverse, then (7,9) would be on the graph of the original function.
If (a,b) is on the graph of the function, then (b,a) is on the graph of the inverse.
Getting to your question, which of the points listed has the inverse listed up in the table?
