the question is
use the definition of continuity to determine if f(x) is continuous at x = 0
if not, give type of discontinuity
f(x) = abs (x+3) x < 0
2x + 1 x = 0
(x+2)^2 - 1 x > 0
the problem im having with is "abs (x+3) x < 0" this part
as far as i know, since x < 0, x is approaching from the left
thus, abs (x+3) = -(x+3) ??????
but 0+3 > 0...? so +(x+3)?????
im really confusing if x+3 has to be negative or positive
someone put me in the right track please !!
