When you graph an inequality, you used a closed dot when you use which
symbols?

Answers

Answer 1
Answer:

You should only use a closed dot for the symbols ≤ and ≥.

When you should use a closed dot?

There are two types of dots used when graphing inequalities, closed and open.

  • We use closed dots when the value where the dot is, is a solution.
  • We use open dots when the velue where the dot is, is not a solution.

So, for exampe in:

x > 3.

We would put an open dot at 3, because the value x = 3 is not a solution, but all the values at the right of the 3 are solutions.

In the other hand, for:

x ≥ 3

Now 3 is in fact a solution, so here we should use a closed dot.

Then, answering the question.

"When you graph an inequality, you used a closed dot when you use which symbols?"
