[ \left|\frac3n+12n+5 - \frac32\right| = \left|\frac2(3n+1) - 3(2n+5)2(2n+5)\right| = \left|\frac-132(2n+5)\right| = \frac132(2n+5) < \frac134n ] Given (\varepsilon>0), choose (N > \frac134\varepsilon). Then for (n\ge N), (\frac134n<\varepsilon), so the difference (<\varepsilon). QED. Chapter 10 – Continuity and Limits Exercise 10.4 Show (f(x)=x^2) is continuous at (x=2).
