Question

Determine lim f(x) {-x x≤2
-------- when f(x)={x+1 25 {6 x>5

Answer 1

just replace x by 5 in formulas 2 and 3 and see if they match.
\[f(5)=5+1=6\] and you get 6 if x > 5 so they match up there. in other words the limit from the left is 6 and the limit from the right it 6 so the limit is 6
