1. The problem statement, all variables and given/known data This may not be the correct place to ask but the problem gives a graph of f'(x)=e^-x^2 with a particular solution f(0)=0. It then asks you to find the limit of f(x) as it approaches infinity using a graphing calculator options .886 .987 1.0 1.414 inf 2. Relevant equations 3. The attempt at a solution I would think I would have to integrate in order to solve this - but I have no idea how to integrate this. My Tnspire comes up with an error message. By fudging I am guessing the answer is .886, but that won't help me if I have to do this on an exam. It is obvious from the graph that it is 1 or less. If someone can point me to some instructions or something I would be grateful.
