@@jasonstarrising I made this for my junior and senior students who were still not understanding how to define domain and range of a graph because they couldn't understand intervals. Some teachers do not teach interval notation at all.
You are a great teacher. The way you explained made it so much easier. It helped me understand Interval Notation & how to graph it on a number line. Thank you a lot!
If the arrow in the inequality points left, shade left on the number line. If the arrow points right, shade right. I made this video so students could better understand how to write intervals to express domain and range. Since domain are all x's, and the x-axis goes left and right, go left if < and right if >. Since range are all y's, and the y-axis goes up and down, remember that up is positive and down is negative on the y-axis. So if the inequality symbol is pointing left < (think left...low...or below), shade down, below the number. If the inequality symbol is pointing right > (think right...raise...as in raise up) and shade up, above the number.
Taking college algebra online over the summer and the examples they give on it are confusing. This helped out so so much. Thank you for all you do!

I still don't understand how do u know when to go left or right

what about {x|7
It's always easiest to understand if the variable is on the left side. So rewrite as x>7
nice pen
They are my favorite. I get them at the Dollar Tree 2 in a pack. Brand is INC or something like that.
