Any help welcomed

You can put this solution on YOUR website!
f%28x%29+=+tanh%28x%5E2%29-1

Alternate form assuming x is real:

f%28x%29+=+sinh%28x%5E2%29%2Fcosh%28x%5E2%29+%2B+1%29+-+1


The domain of a function is: R (all real numbers)
interval:
(-infinity, infinity)
range:
y-intercept is (0,+-1 )
so, range is :{ f%28x%29+element R :+-1%3C=f%3C0 }
