A piecewise function is given. Use the function to find the indicated limits, or state that a limit does not exist.
(a) lim is over x>d – f(x), (b) lim is over x>d + f(x), and (c) lim is over x>d f(x)
x^2  5 if x < 0
f(x)= 2 if x >0 ; d = 3
1. (a)5 (b)2 (c)does not exist
2. (a)4 (b)4 (c)4
3. (a)2 (b)5 (c)does not exist
4. (a)5 (b)2 (c)2

what is wrong with answer 2? Have you worked this? Iwill be happy to critique your thinking.
