Question

Find the domain and range of a real function f(x) =1/(1-x^2)?

Answer 1

domain = R-[-1 , 1] is that correct

Answer 2

then wat is the range??

Answer 3

hw to find it

Answer 4

solve for x the equation
\[ y=f(x)=\frac{1}{1-x^2} \]
you'll get something like x=g(y) and do for this whatever you did to find the domain of f

Answer 5

\[ 1 \over 1 - x^2\]

Answer 6

what values of x is not possible? and what outcome is not possible?

Answer 7

0 is not possible
