Hi, I know that the range of an inverse function is the domain of the function, but how do you work it out if you dont know it? You could sketch a graph but doesn't that get tricky for hard complicated functions. For example:

[tex]\frac{3x}{x+1} - \frac{x+7}{x^{2}-1}, x > 1[/tex]

If i find the inverse function, who would i then find the range of it?

Thanks

[tex]\frac{3x}{x+1} - \frac{x+7}{x^{2}-1}, x > 1[/tex]

If i find the inverse function, who would i then find the range of it?

Thanks
