Find domain and range of the real function f(x) = 3/ 1- x^2 Share with your friends Share 0 Vijay Kumar Gupta answered this Consider the following function. fx=31-x2The domain is the set of all points at which the function is defined.The given function is a rational function, so it is defined for non zero denominator.Thus the function f is defined if 1-x2≠0 1-x1+x≠0 x≠1,-1Thus the domain of given function is Df= R--1, 1The range is the set of all the functional values at the points of domain. Thus the range of the function is, Rf= fx: x∈R, x≠1,-1 0 View Full Answer
