How do you graph #-x>=20# on the coordinate plane?
See a solution process below:
graph{x + 20 <= 0 [-100, 100, -50, 50]}
The boundary line is a solid line because the inequality operator contains an or equal to clause

To graph the inequality -x ≥ 20 on the coordinate plane, follow these steps:
-
Start by graphing the line x = -20. This is a vertical line passing through the point (-20,0) on the x-axis.
-
Since the inequality is -x ≥ 20, the shaded region represents all the points where -x is greater than or equal to 20. This means we shade everything to the left of the line x = -20, including the line itself because it's greater than or equal to 20.
-
The shading should extend infinitely to the left from the line x = -20, covering all the points where -x is greater than or equal to 20.
That's how you graph the inequality -x ≥ 20 on the coordinate plane.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
