Domain And Range From A Graph Of A Continuous Function
We could continue the graph in the negative and positive.
Domain and range from a graph of a continuous function. In a continuous graph to determine the range you should focus on looking bottom to top of the graph. This section is related to the earlier section on domain and range of a function there are some functions that are not defined for certain values of x. Put any number into the sin function in your calculator.
The range is the set of possible output values which are shown on the latex y latex axis. When looking at a graph the domain is all the values of the graph from left to right. View domain and range pdf from history 22225 at john champe high school aldie.
Continuous and discontinuous functions. Continuous functions are graphs that don t have or. 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.
If you re seeing this message it means we re having trouble loading external resources on our website. The graph of f x is continuous i e. Given the graph of a function determine its domain or range.
Another way to identify the domain and range of functions is by using graphs. The domain of y sin x is all values of x since there are no restrictions on the values for x. Break in the curve in the respective domain.
If a 1 y increases as x increases as seen from graph. In a continuous graph to determine the domain you should focus on looking left to right of the graph. The domain is all x values or inputs of a function and the range is all y values or outputs of a function.
