Question

Please help which of the following conditions does the graph meet?

Answer 1

Answer: Choice A

Explanation:

The left shaded portion describes all (x,y) points such that x < -1. Basically, it's any point to the left of that dashed vertical line through x = -1. Points on the dashed line are not part of the solution set.

The shaded portion on the right side visually describes any point (x,y) such that $x \ge 2$. Here we have a solid boundary line, and any point on this line is included in the solution set.

These two regions are connected with an "or" because you can be in either region, but not both at the same time.

Notice how y is never mentioned other than when we talk about (x,y). This is because we're just dealing with the x axis number line.

Answer 2

Answer:

{(x,y):x≥-1) or {(x,y):x≤2)
