How do you find domain and range? Note that I am a beginner in algebra.?

Answer 1

Range is the biggest number minus the smallest number.

An example:

1 2 3 4 5 6 7 8 9 10

You would take 10-1= 9 So your range would be nine.

A Domainnnn... is the set of possible x-values or independent variables.

I hope i've helped you

Answer 2

In mathematics, a function relates each of its inputs to exactly one output. A standard notation for the output of the function f with the input x is f(x). The set of all inputs that a function accepts is called the domain of the function. The set of all outputs is called the range.For example, the expression f(x) = x2 describes a function, f, that relates each input, x, with one output, x2. Thus, an input of 3 is related to an output of 9. Once a function, f, has been defined, we can write, for example, f(4) = 16.

It is a usual practice in mathematics to introduce functions with temporary names like f; in the next paragraph we might define f(x) = 2x+1, and then f(4) = 9. When a name for the function is not needed, often the form y=x2 is used.
If we use a function often, we may give it a permanent name as, for example,

Answer 3

well, if ur doin algebra, then the domain means the 'x' in the problem, and the range is the 'y' in the problem

i hope that helps
i havent done algebra in a year or so
xD

good luck!
:]

Answer 4

domain=all inputs
range=all output
