When you see this equation it means you are try to let x approaches a.
You may have a question why can't we just write it as
some times we can't tell what is the F(a) equals to.
example 1
But If a = 1 then you will get
Denominator can't be 0 so it is undefined at that point.
But in the graph if a = 1 it looks like it is than f(x) = 4
