Hello,

I took this a long time ago and I need to refresh my mind about it, can you please help ?

The function is defined by for

Find the inverse function stating its range and domain, and sketch the inverse function .

Now I do now really want the sketch since I will try finding that out myself.

But how do we find ?? What I remember is that im supposed to re-arrange the equation so that it is .. but wont that change the domain and range ?

Please help,

Kind Regards,

Z
