Evaluate the limit to infinity and negative infinity from a graph

The video tutorial explains the concept of limits in calculus, focusing on how functions behave as X approaches infinity or negative infinity. It discusses the difference between the actual value of a function at a point and the value it approaches, using limit notation. The tutorial also covers how to evaluate function values and the importance of considering both left and right approaches when determining limits.
