CALLING EXPERTS!!! PLEASE HELP

Answer 1

Green answers in order of 1-7 as green appears

Just show the ones at start of each answer in bold

1) x ≥ -2 closed circle start opp/s x ≤ 0 closed circle stop

2) x < -2 open circle stops opp/s x ≥ 0 closed circle start

3) x > 2 open circle starts opp/s x ≤ 0 closed circle stops

4) x ≤ 2 closed circle stops opp/s x ≥ 0 closed circle starts

5) x < 2 open circle stops opp/s x ≥-6 closed circle starts

6) x > 2 open circle starts opp/s x ≤ 6 closed circle stops

7) x < -2 open circle stops opp/s x ≥ -6 closed circle starts

Explanation:

Rule 1 closed circle is ≥ right open circle shows > right

Rule 2 closed circle is ≤ left open circle shows < left

Rule 3 with inequalities on line x > 2 means it starts from this value and moves right.

Rule 4 with inequalities on line x < 2 means it ends in this value.

Rule 5 Remember rule 3 and rule 4 for direction start and stop

remember rule 1+ rule 2 for choice of closed circle etc.

Answer 2

The circle is open if the inequality is greater than (>) or less than (<) and closed if the inequality is greater than or equal to (≥) or less than or equal to (≤)
If the arrow points to the right (—>) towards bigger numbers, x (whatever number is on the line) will be GREATER (> or ≥)
If the arrow o points to the left (<—) towards smaller numbers, x will be LESSER (< or ≤)

1. Starts at -2 with a closed circle and goes in the positive direction —>
So x ≥ -2
2. Starts at 2 with an open circle and goes in the negative direction <—
So x<2

And the rest use the same method.
