Question 1006510
A) locate 3 in the "x" row. The value right below it is 6


So f(3) = 6


--------------------------------------------------------------


B) Locate 3 in the f(x) row. The value above it is 6


So if f(x) = 3, then x = 6


--------------------------------------------------------------

C) 

Locate 4 in the f(x) row. The value above it is 11


So f^-1(4) = 11


--------------------------------------------------------------


D) 


Locate 4 in the "x" row. The value below it is 0


So if f^-1(x)=4, then x = 0
