3do mention the domain and codomain to check if the function is bijective or not .........
113sorry a small error ...... make it .........
log√x+1/1-x = y ............
clearly its definded only for x ε [1,0) U (0 , - 1)
3take componento dividento on both sides
we get
1+y/1-y = 10^2x
take log
and we get x = log√y+1/1-y
replace x by y ,,,
