I have a question in my text that I don't quite know what to do with:
use the definition of continuity and the properties of limits to show that the function is continuous at the given number a
f(x)=(x + 2x^3)^4, a=-1
so far I have gotten:
(lim x + 2 lim x^3)^4 x->a x->a
- is this correct so far?
- if so, what is my next move?
Thanks in advance!!!! (loving this site by the way :-))
