How to evaluate the limit at the end of a radical graph left right and general

The video tutorial explains the concept of general limits, emphasizing that for a general limit to exist, both the left and right hand limits must be the same. The right hand limit at X = -1 is discussed, showing it approaches 1, while the left hand limit does not exist due to the absence of values to the left of -1. The video also addresses common misconceptions about evaluating limits at X = -1 and introduces the concept of H of X, explaining how it relates to the height of the function as X approaches -1.
