(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Analysis Question, I posted yesterday!

1. The problem statement, all variables and given/known data

Define f(x)=2x, x is rational and x+3 when x is irrational. Find all points where g(x) is continuous and prove continuity at these points

2. Relevant equations

From analysis homework and using the real definition of continuity

3. The attempt at a solution

what I did was I took the limit as x approached 3 of x+3, and found for 0<|x+3|<epsilon which will equal delta, then |X+3-6|=|x-3| which is less than epsilon. So then I know that the limit of the function =the limit of f(3) so therefore continuous at x=3. Is there anymore that I need?

Thanks,

Michelle
