Chapter 3 Essay

Period: 6

In chapter three, section 1, we learned about graphing and writing inequalities. The symbols we are going to use a lot are <-less than,>- greater than ≤-less than or equal to, ≥-greater than or equal to. You may be asking how would I graph these inequalities, well you have to make sure it comes down to a variable and one of those symbols with a number after it. Like, this example would be x<5. To determine whether it's open or closed is when if it's greater than or equal to or less than or equal too, or the greater & less than sign with a line under it. If it's a normal sign you would leave the circle you have to put on the graph open. If it's not you color it in, and which direction it should go, well you probably don't know, but I'm here to tell you. To determine which direction to point your arrow on the graph you have to draw on every problem would be whatever way your symbol is pointing. Remember the variable has to be on the left side.
