We can define general Properties of LIMITS. And we can also define basic mathematical Operations on Limits?
Do you think that these "general" Properties and Operations would be useful? Why? Can you predict what types of problems could be solved if basic operations on Limits were proven to be mathematically correct?
General Limit PROPERTIES and OPERATIONS allows us to apply the idea of limits to many different problems and also to prepare the foundation for integral and differential calculus.

Suppose we have 2 functions:f(x) = x2 + 1 and g(x) = x – 4 Let's compare the resulting limits of functions (involving f(x) and g(x)) obtained by Direct Substitution (only) AND then by using the Properties and Operations on Limits.
Some Examples

Let's examine some limits involving f(x) and g(x). [Note: f(x) = x2 + 1 and g(x) = x – 4]Using Direct Substitution, let’s find the limits of the functions below.

Let's examine other limits involving f(x) and g(x). [Note: f(x) = x2 + 1 and g(x) = x – 4]And now let's use the Properties and Operations on Limits to find these limits.
