Use the continuity and the properties of limits to show that the function is continuous at the given number.

1. f(x)=( x+2x^3)^4, a=-1

2. f(x)=(2x+3)/(x-2) ,(2,infinity)

Show us what you have done.

In particular what are the "properties of limits" and what is the definition of "continuous function"?
