Prove the following:

(a)

lim(2n256n2+3n)=3

Here for the numerator n must be greater than or equal to 2 right? And for the denominator n must be greater than or equal to 3? Can you assign any n to create an upper bound?

example N=max{ 3, epsilon?}

Please help constructing this proof with >0, Let N=max{}...format.

(b)

limn+1n=0

Please help as described in part (a) as well for this problem. Thank you.
