Given: x=y^2 + 1 ------> Finding "y":
Isolate "y" by moving terms all to the left (or right).
x-1=y%5E2
Raised both left & right terms to 1/2 :
%28x-1%29%5E%281%2F2%29=%28y%5E2%29%5E%281%2F2%29---->%28x-1%29%5E%281%2F2%29=%28y%5E%28cross%282%29%29%29%5E%281%2Fcross%282%29%29 or,
highlight%28y=sqrt%28x-1%29%29

Thank you,
