  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
    
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

when is it below the x-axis?

arctic ore
#

you also need to exclude -3

shy cedar
arctic ore
#

it’s on the axis

shy cedar
#

(-infinity, 0)

#

that includes -3 tho

arctic ore
#

because when x = -3 the graph lies on the x-axis and is therefore not negative

shy cedar
#

so

#

uh

#

(-infinity, -3) U (-3, 0) U (4, infinity)

#

graph is negative

#

cuz u dont include -3

#

and its g(x) less or equal to 0
(-infinity, 0] U [4, infinity)

cuz u include the x intercept
