Domain And Range In Algebra

For the domain and the range we approximate the smallest and largest values since they do not fall exactly on the grid lines.

Domain and range in algebra. To give the domain and the range i just list the values without duplication. The domain and range of a function is all the possible values of the independent variable x for which y is defined. Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the x axis.
