Given the coordinates of the function;
f(x) = {(7,3), (5,3), (9,8).(11,4)}
The inverse of any coordinate points is gotten by changing the y coordinate valuewith the x coordinate values i.e y = x
f-1(x) = {(3,7), (3,5), (8,9), (4,11)
You can see that the x coordinates has been swapped with the y coordinates.
Similarly;
g-1(x) = {(7, 5),(5,3), (9,7), (11,9)}
