Domain And Range Of A Graph For Dummies

I make short to the point online math tutorials.

Domain and range of a graph for dummies. The domain includes the values that go into a function the x values and the range are the values that come out the or y values. F of negative 1 is negative 3. Negative 2 is less than or equal to x which is less than or equal to 5.

Keep in mind that if the graph continues beyond the portion of the graph we can see the domain and range may be greater than the visible values. A sine curve represent a wave the repeats at a regular frequency. Based upon this graph the maximum is equal to 1 while the minimum is equal to 1.

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 latex x latex axis. Another way to identify the domain and range of functions is by using graphs. The range is the set of possible output values which are shown on the y axis.

The range is the set of possible output values which are shown on the latex y latex axis. What is its domain. If you give me an x anywhere in between negative 2 and 5 i can look at this graph to see where the function is defined.

The x values span all real numbers as there is no limit to the input fo a sine function. 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. So once again this function is defined for negative 2.
