How Do You Find The Domain And Range Of The Graph Of A Function, Using Interval Notation?
Many students find it very difficult to express the Domain and the Range of a function or the graph of a function using Interval Notation. This article will show us how to find the Domain and the Range of the graph by using a rectangle to box in the graph. The Domain of the graph of a function is the set of all real numbers x that allows the graph to exist, that is any x that causes the graph to be undefined or imaginary is not included in the domain. That is consider the Domain the x-distance (how far from left to how far right does the graph go).Please click on the Image for a better understanding. Similarly, the Range of the graph of a function is the set of all real numbers y from the lowest point of the graph to the highest point of the graph. Consider the Range the y-distance (how far from the bottom to how far up does the graph go). Please click on the Image for a better understanding. Now we can see the Domain and the Range of the graph that is inside the rectangular box. The D
