We have these two graphs, and these two functions:
A) (F+G)(x)
and
B) (F/G)(x).
And the question is asking what the domains of these two functions are. I am having a lot of trouble understanding how to get to the proper answers. If anybody could explain this question I would be very grateful.
Answers:
A) (-∞, -1]u(1,2]u(3,∞)
and
B) (-∞,-4)u(-4,-1]u(1,2]u(3,∞)
