Cubic Function Graph Domain And Range. Below is a graph of the cubic function f x - x3 2 x2 3 x -1. Where a b c and d are real numbers and a is not equal to 0.
The same applies to the vertical extent of the graph so the domain and range include all real numbers. Since no values of x are negative domain is all real numbers. Then since the vertex is the low point take the primary square root of 4 to get 2 so range is y 2.
This function is increasing throughout its domain.
Determine the properties of a cubic function in standard form. Fx x 2. C Since there is only one output value we list it by itself in square brackets. The same applies to the vertical extent of the graph so the domain and range include all real numbers.
