Domain and range from the graph of a parabola duration. The domain of a parabola consists of the x values that create a. The range of a function is all the possible values of the dependent variable y. The domain and range of a parabola essentially refer to which values of x and which values of y are included within the parabola assuming that the parabola is graphed on a standard two dimensional x y axis when you draw a parabola on a graph it might seem weird that the domain includes all real numbers because your parabola most likely.
The example below shows two different ways that a function can be represented. The range of a function is the set of output values when all x values within the domain are evaluated into the function commonly referred to as the y values.
