Domain of a function desmos. If you allow the value of the modular function to be less than a small number say mod x 3 0 01 then you will see the points you expect. For example y 2x 1 x 3 would graph the line y 2x for x values between 1 and 3. To find the domain of a function just plug the x values into the quadratic formula to get the y output. The domain of a function is the collection of independent variables of x and the range is the collection of dependent variables of y.

This function is the logarithm with base 2 log 2 x. Ryan for some reason the desmos engine doesn t do mod x 3 0 perhaps it s graphing an infinately small point. Describe and predict the effects of changes in a and c on the graph of y ax 2 c. Autofill tables by defining column heads with functions or build a movable point to trace a path along a particular curve.

Domain the input values in a given function is called domain of a function. To find the range of a function first find the x value and y value of the vertex using the formula x b 2a.

To limit the domain or range x or y values of a graph you can add the restriction to the end of your equation in curly brackets. From piecewise functions and implicit relations to including sliders within your restrictions desmos makes it easy to control what you see in the coordinate plane. The domain calculator allows you to take a simple or complex function and find the domain in both interval and set notation instantly.
