thats right !
OpenStudy (dumbsearch2):
Thank you :) So it's D?
ganeshie8 (ganeshie8):
Yep ! we need to include 3 in the domain cos there is a filled circle at x = -3, so the input -3 produces a value of -1 The arrow on top right corner indicates that the ray goes forever in that direction - so the domain would be : [3, infty)
