Question

find the domain and range of the real function f (x)=1/√x^2 -1​

Answer 1

Answer:

F(x)=1/x^3+x-2

Domain = all real values except 1

                               or

                         R-{1}

This is bcz on drawing the graph of f(x) =1/x^3+x-2 ; the graph meets the x-axis at only one point (1,0) ... which will be undefined...so the domain is all real numbers except 1
