Question

f(x) = {(7,3), (5,3), (9,8).(11,4)}g(x) = {(5, 7),(3,5), (7,9), (9,11)}a) f-1(x)b) g-1(x)

Answer 1

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)}
