How do you write answers in interval notation

You can use any letters, but they must be in the same format - a variable followed by another variable in parentheses. The numbers in interval notation should be written in the same order as they appear on the number line, with smaller numbers in the set appearing first.

These brackets say, "Hey, let me include the endpoint," but I'm not going to include them, so I'm going to put the parentheses right over here. Most students remember the infinity sign and the notation for all real numbers.

That is, the set of numbers goes all the way to positive infinity. Determine the values of the variable that make the inequality true. Register for a New Patient Information Session.

In this case, we have less than zero, so we want all of the negative sections. C denotes the set of all complex numbers. To express the solution graphically, draw a number line and shade in all the values that are solutions to the inequality.

When and what do they mean? So we're not going to include negative four. We look at the next box and I ask what the parenthesis means for the interval. We would interpret this interval notation as representing the total group of numbers as the union of two other groups.

Tip If there are other intervals of the variable, connect them with the union symbol "v.
