Question

Which points are on the graph of the inverse?

Answer 1

The points (1,-1) and (0, 0) lie on the line y=x and will be included on both graphs. 

When a graph is inversed, the coordinates are also flipped. (-9, 3) also switches the sign, which is not a part of the inverted graph. 

The other option (4, 2) is a flip on the given coordinates (2, 4) and would be present on the inverted graph. 

Answer 2

the difference of a function and its inverse is found by switching x and y
so if the function is (2,3)...then its inverse is (3,2)

(4,2)....correct
(1,-1)...correct
(0,0)...correct

I agree with ur answers
