0 can't be the answer as the the slope is 1/2 at x = 1 and as x tends to infinity f'(x) remains always positive and tends to zero, hence the function keeps increasing from x = 1 and approaches some maximum value which is less than infinity but greater than 1.Log in to reply

If you know how to solve this differential equation you can find the function and hence the limit. OR if you just need the answer try WolframAlpha or something like that to solve the differential equation.

Hope this would help! – Lokesh Sharma · 4 years ago
