Properties of Limits
Let b and c be real numbers, let n be a positive integer, and let f and g be functions with the following limits.
lim f(x) = L and lim g(x) = K
x-->c
x-->c
Scalar multiple:
lim [b f(x)] = bL
x-->c
Sum or difference:
lim [f(x) ± g(x)] = L ± K
x-->c
Product:
lim[f(x) * g(x)] = LK
x-->c
Quotient:
lim f(x) / g(x) = L / K, privided Kdoes not = 0
x-->c
Power:
lim [f(x)]n = Ln
x-->c
