Question

How do you graph `x >= -2`?

Answer 1

see below

Explanation:

graph{x >= -2 [-11.25, 11.25, -5.625, 5.625]}
all the shaded area satisfies the equation `x>= -1`

Answer 2

All points on the `xy-`plane where `x>=-2 forall y in RR`
An area to the right of and including the vertical line through the point `(-2,0)`

Explanation:

`x>=-2`

First let's consider the limiting case where `x=-2`.
This can be represented graphically on the `xy-`plane as a vertival line through the point `(-2,0)`

Now, `x>=-2` can be represented by the area positive ("right") of that line and the line itself for all `y in (-oo,+oo)`

This area is indicated as shaded area below extended beyond all bounds in `y and x^+`

graph{x>=-2 [-10, 10, -5, 5]}
