PreCalc
posted by Sarah .
I'm stuck on a precalc problem. I need to find y as a function of x, where the constant c is a positive number for In(y1)+In(y+1)= x+c
express your question as
ln[(y1)(y+1)] = x+c
change that to exponential form
e^(x+c) = (y1)(y+1)
e^(x+c) = y^2  1
y^2 = e^(x+c) + 1
y = ± sqrt(e^(x+c) + 1)
