graph{-x-2 [-10, 10, -5, 5]}
linear slanted line that goes to infinity continuously on both sides
Explanation:
Here's the graph. graph{-x-2 [-10, 10, -5, 5]}
to do inverse, you just flip the
Since it's a linear slanted line that goes to infinity continuously on both sides, there will be a horizontal line that passes through any point on the graph
