complete the table of contents for the inverse

Question

Consider the function g(x) represented by the table below: 

x	-6	-4	-2	0	2	4	6
g(x)	4	0	2	6	-4	-6	-2

Complete the table of values for the INVERSE, g−1(x), in the table below: 

x	-6	-4	-2	0	2	4	6
g−1(x)

Answer 1

g^-1(x) = 4, 2, 6, -4, -2, -6, 0

just switch the x values with the corresponding g(x) values to get the g^-1(x) values

for (x,y) the inverse points are (y,x)
