Question: Given a function f : R R explain what is wrong if we define it as f ( x ) = x 2 + 1

Given a function f:RR explain what is wrong if we define it as f(x)=x2+1x-1. How would you need to modify the domain the definition for this to be a function? Does your modified function have an inverse? Explain why. (hint: There are many mays to go about this, if you try one uay and it is too hard, consider the alternatives.)
