# How to find the domain of a line

Math can be difficult to understand, but it's important to learn How to find the domain of a line.    ## How to get the domain and range from the graph of a function

Graph m(x) = x m ( x) = x on the Cartesian plane to the right. The domain of m(x) m ( x) is: The range of m(x) m ( x) is: If any of the above do not exist, leave the answer box blank. 1 2 3 4 5 6 7 8 9 10 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 1 2 3 4 5 6 7 8
` ## Determine Domain and Range from a Graph

Step 1: Draw the graph. Step 2: Find the possible values of x where f (x) is defined. Here the x values start from -2 and ends in 2. Step 3: The possible values of x is the domain of the function. \therefore ∴ the domain of the circle
