Domain and range of a relation in math:
Let R be a relation in a set A. Then, the set of all first coordinates of elements of R is called the domain of R, written as dom (R) and the set of all second ..

domain and range for relations and functions domain and range maps graphs
Question : ive got an algebra test pretty soon and most of the questions are gonna be on functions. i still dont know how to find the domain/range for functions like these:
f(x) = 3x + 1
f(x) = |x - 2|
f(x) = x/2 + 1
(in the last equation, 2 is an exponent of x)
also, how do you figure out the domain/range of functions on a graph? hellllllpppppppppp. t.y.
Answer : the domain is all of the possible x values that are valid and the range is all of the possible values of f(x). For the first one, the domain and range are all real numbers. For the second, the domain is all real numbers and the range is all real numbers greater than or equal to 0. For the third one the domain is all real numbers and the range is all real numbers greater than or equal to 1. When you are looking at a graph, the domain is all of the x values that you can have and the range is all of the y values you can have.

Question : f(t) = sec *t/4
I don't know how to find the domain and range of the function mentioned above. Help?
Answer : Graph it and you'll see the range falls from -1 to 1. The domain is all real numbers, I believe as you will result in decimal values.
