Approachment As the values of some set of inputs tend to get closer and closer to a number, the corresponding list of outputs get closer and closer to some number. The set of x values; values in the domain of some function approach Some specific number, may or may not be in the domain of the function The set of function outputs; values in the range of some function approach Some specific number, may or may not be in the range of the function Wednesday, January 16, 2019 MAT 145
