Two main methods of geoengineering are gaining traction: Greenhouse gas removal (GGR) technologies would reverse the runaway greenhouse effect by removing carbon dioxide from the atmosphere.
The cause of the injury is the lack of proper cleaning.
C. It’s the only choice that limits a right. Think about it, the rest are granting rights.
Answer:
D. The last option
Explanation:
You can't divide by 0, so find out when the given function is discontinuous.

You can see that x is discontinuous at x=-1,1, so find a piecewise function that fill in those gaps.
Plug x=-1,1 into your function to find out what values you need to fill in. But of course it's discontinuous at those points, so plug in a number near x=1 and x=-1. I chose x=-1.1 and x=1.1


so we need to fill in 2 at x=-1, and fill in 4 at x=1
