Definition of a Limit
Let f(x) be any function and let a and L be numbers. If we can make f(x) as close to L as we please by choosing x sufficiently close to a, then we say that the limit of f(x) as x approaches a is L or symbolically,
Theorems on Limits
- , c=any constant
- , a=any real number
- , n=any positive integer and f(x)>0 if n is even.
