find the inverse of f(x)= 3x²/ x²+1. what is the domain of the inverse and what must be done to ensure that the inverse is a function.
i found that the inverse function is ±(square root of) x/3-x
can anyone help me wiht the rest?
First this function does not have an inverse for all real numbers. However if you restrict the domoanin then it does, . The range of the inverse function is the same as the domain of the original map.
