find the domain and range of f(x)=x square/1+x square Share with your friends Share 37 Anuradha Sharma answered this Given, fx=x21+x2As we can say that 1+x2≥0 because x2≥0So function can takes all the values of x so domain is x∈R.Now Let y =x21+x2y+yx2=x2x2=y1-y or x = y1-yNow domain of this function will be the range.Here we can see that , y can take all the values exceot 1 so, range = y∈R-1 -199 View Full Answer
