Question

Describe the graph of the solution​

Answer 1

First, we want to note two things:

• We have a solid circle at -10, so -10 IS part of the solution.
• We have shading to the right of -10, meaning we also need to include numbers to the right of -10, or numbers greater than -10.

We can describe this with an inequality: x ≥ -10
Be sure you use ≥ and not >, since -10 is included.

We can describe this with interval notation: [ -10, infty )
Be sure you use [ and not ( on -10, since -10 is included.

You can also use set-builder notation: x
