 In this video, we present the solution to question number one for practice exam number two for math 1210, in which case we're given a function f illustrated by the graph right here, and we're asked to compute the limit as x approaches negative infinity. So we're trying to identify the limit of the function based upon the behavior to be on the graph. If we're looking for the limit as x goes to negative infinity, we're trying to see the trajectory of the function as it continues to the far left of the graph. So continuing on, we see that there appears to be some type of horizontal asymptote on the function which appears to be around y equals one. And so from that observation, given this is a multiple choice question, we would then identify the correct answer as choice B, y equals one is the horizontal asymptote of this function.
