What is the limit of a function?
The limit of a function f(x) is a value L (if it exists), to which the function f(x) gets arbitrarily close to, when x approaches c.
What are the two ways a limit can be denoted?
What is a right-hand limit?
A limit, when x tends to c from the right hand side.
What is a left-hand limit?
A limit, when x tends to c from the left.
Which condition has to be satisfied, so that a limit exists?
Right hand limit equals left hand limit.
When calculating a limit,
which value are we not allowed to substitute instead of x?
∞
When dealing with limits as x -> ∞, which property can be used.
