find the domain and range of real function f(x)=1/(1-x2) Share with your friends Share 4 Anuradha Sharma answered this Let y = 11-x2Now thisfunction is defined for all x except at x = ±1x∈R-1,-1 DomainNow for finding range find x in terms of y and then domain of that function will be the range of the function, y = 11-x21-x2=1y⇒x =y-1yNow this is defined for y-1y ≥0 except y ≠0 y ∈-∞,0∪[1,∞)So range of fx is -∞,0∪[1,∞) 15 View Full Answer
