How do you find the limit of f(x) = (x^2 - 1) / ( x + 1) ^2 as x approaches 0? Calculus Limits Determining Limits Algebraically 1 Answer Maharshi ยท Jim H Feb 27, 2016 lim f(x) = -1 as x -> 0 Explanation: f(x) = (x^2-1)/(x+1)^2 f(x) = ((x+1)(x-1))/((x+1)(x+1) f(x) = (x-1)/(x+1) So, lim f(x) = (0-1)/(0+1) = -1 as x goes to zero.
