Find Domain And Range Of A Graph Using Interval Notation

F of negative 1 is negative 3.

Find domain and range of a graph using interval notation.

Latex f left x right 2x left x 1 right left x 2 right latex 7. Hence the domain in interval notation is written as 4 6 in inequality notation the domain is written as. Solution to example 1 the graph starts at x 4 and ends x 6. Negative 2 is less than or equal to x which is less than or equal to 5.

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. For all x between 4 and 6 there points on the graph. 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.

Here are some examples illustrating how to ask for the domain and range. In interval notation the domain is 1973 2008 and the range is about 180 2010. How do you graph a piecewise function. Identify the intervals to be included in the set by determining where the heavy line overlays the real line.

Domain and range tips for entering queries. At the left end of each interval use with each end value to be included in the set solid dot or for each excluded end value open dot.

Square root of cos x. To avoid ambiguous queries make sure to use parentheses where necessary. Domain of log x x 2 1 x 2 1 domain. The graph may continue to the left and right beyond what is viewed but based on the portion of the graph that is visible we can determine the domain as latex 1973 le t le 2008 latex and the range as approximately latex 180 le b le 2010 latex.

Given a line graph describe the set of values using interval notation. Finding the domain of a function cool math has free online cool math lessons cool math games and fun math activities. Find the domain of 1 e 1 x 1 function domain. F of negative 2 is negative 4.

For the following exercises find the domain of each function using interval notation. Enter your queries using plain english.
