Sorry this is the last question i was confused with on my new review sheet. However I'm pretty sure I wont figure this answer out as soon as i post (sorry about that) so im sure this time i need help

Define f : R->R as follows:

f(x)= 8x if x is a rational number

f(x)= 2$\displaystyle x^2$+8 if x is an irrational number.

use sequences to guess at which points f has a limit, then use $\displaystyle \epsilon$'s and $\displaystyle delta$'s to justify your conclusions.
