1. if f(2)=4 can you conclude anything about the limit of f(x) as x approaches? explain your reasoning.

2. if the limit of f(x) as x approaches 2 is 4, can you conclude anything about f(2)? explain your reasoning.

We have two questions. I will answer them in the order you have posted them.

1. If f(2) = 4, can we conclude anything about the limit of the function as x approaches 2.

The answer to this question is 'No'. The reason is pretty simple, the limit of a function doesn't depend on the actual value of the function at a point. This can be understood very well with an example of a function with a jump discontinuity. At a jump discontinuity, the value of function may exist, however limit doesn't exist.

2) If the limit of f(x) as x approaches 2 is 4, can we conclude anything about f(2)?

The answer to this question is 'No'. The reason is, the value of a function doesn't depend on limit of the function at a point. This can be understood very well with a question where we have a hole. A rational function with a hole is a very good example that will clarify this question. Limit of a function at a point where we have a hole in the function will exist, however, value of function will not exist.

practice. practice. practice.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
