Domain Math Is Fun
X y and is alternatively denoted as.
Domain math is fun. Since a function is defined on its entire domain its domain coincides with its domain of definition. A simple function like f x x 2 can have the domain what goes in of just the counting numbers 1 2 3 and the range will then be the set 1 4 9. Basic definitions in algebra such as equation coefficient variable exponent etc.
The function must work for all values we give it so it is up to us to make sure we get the domain correct. The domain of 1 x. In the function machinemetaphor the domain is the set of objects that the machine will accept as inputs.
For other linear functions lines the line might be very very steep but if you imagine zooming out far enough eventually any x value will show up on the graph. All the values that go into a function. When the function f x x2 is given the values x 1 2 3 then the domain is simply those values 1 2 3 domain range and codomain.
For k 12 kids teachers and parents. Domain function range. Two ways in which the domain and range of a function can be written are.
Change the domain and we have a different function. Interval notation and set notation. In fact the domain is an essential part of the function.
F x x 2. The function f x x2 has a domain of all real numbers x can be anything and a range that is greater than or equal to zero. The function s domain is all real numbers because there is nothing you can put in for x that won t work.
