What is interval notation?
Interval notation is a way to represent a set of real numbers on the number line. It consists of two numbers separated by a comma, and the numbers are enclosed in either parentheses or square brackets.

How do you find interval notation?
To find interval notation for a set of numbers, identify the minimum and maximum values of the set, and then use the appropriate symbols to represent the set. To express a set of numbers that includes both the minimum and maximum values, use square brackets [ ] for the endpoints of the set. To express a set of numbers that does not include the minimum or maximum values, use parentheses ( ) for the endpoints of the set.

Domain and Range Calculator: Step-by-Step Function Analysis
Avoid confusion about open and closed intervals when finding the domain and range of a function. If the endpoint is not included (e.g., division by zero), then use the parentheses ( ) If the endpoint is included (e.g., square root boundary), then use the brackets [ ] Example: [5, ∞) means x = 5 is included, while (5, ∞) means it is not included.

The values taken by the function are collectively referred to as the range. For example, the function Start Power, Start base, x , base End,Start exponent, 2 , exponent End , Power Endx2 takes the reals (domain) to the non-negative reals (range). The sine function takes the reals (domain) to the closed interval [-1, 1]-1, 1 (range).

October 6, 2021 - The answers are all real numbers where \(x<2\) or \(x>2\). We can use a symbol known as the union, \(\cup\),to combine the two sets. In interval notation, we write the solution:\((−\infty,2)∪(2,\infty)\). In interval form, the domain of f is \((−\infty,2)\cup(2,\infty)\). ... How To: Given a function written in equation form including an even root, find the domain.

r/MathHelp on Reddit: Domain in Interval Notation
January 24, 2019 -

Easy enough, I need to find the domain for the function f(x)=(-4/3)x+(2/3). It should be (-infinity, infinity) because there are no restrictions on x, but for some reason my online homework (web assign) won't take the answer. I've double checked on a number of online calculators and such and they all confirm my answer. Is there something I'm missing or am I just screwed out of that homework point?

Edit: Link to a SS of the question with what I think is the right answer filled in. https://imgur.com/a/dqIyXCu

Thanks

In the above example, the lowest y coordinate is y=0 achieved when x=3 is plugged in. The larger the x value plugged in the larger the y coordinate we obtain. Thus, the Range is \( y>=0 \) or \( [0,\infty ) \) in Interval Notation. What's another way to think of Domain and Range?
