How are domain and range different?

Answer 1

The domain is the set of values that the independent variable of a function can assume. For example
f(x) = 1/(x-1)
has as its domain the set of all real numbers --except-- 1 (since at
x=1 the denominator is 0 and 1/0 is undefined)

The range is just the set of values that the function can have. In the above example, thee range of the function is the set of all real numbers. But in something like |x|, even 'tho the domain of x is all of the reals, the range is just the set of all the positive reals and 0.

Answer 2

Domain is the x value and range is the y value.

For this set of numbers (2, 7) (6, 8) (5, 4)

Domain = (2, 5, 6)
Range = (4, 7, 8)

Answer 3

The domain incorporates all of the x-values that the graph uses, and the range incorporates all of the y-values that the graph uses.
