The distance to the surface of the water in a well can sometimes be found by dropping an object into the well and measuring the time elapsed until a sound is heard. If T1 is the time (measured...

would it be... a. y=1-x^2 b.y=sqrt(x^2-1) c. y=squrt(1-x^2) d. none of these

The problem I'm stuck on is 1=ln(x-1)+e^(x-2). I solved this by graphing but I can't figure out how to isolate x algebraically since when I try to exponentiate or ln each side, the other operator...
