Domain and Range of a function: steps for finding

[UMBCstudent]

Hi everyone! I need help with the steps for finding the domain and range of a function. Can anyone help me?

 

[Kitkatnesser]

are you looking for the domain and range of a graph from a function? or a line graph?
The Domain is all of the x value or numbers on the x axis
and the range is all the numbers that are on the y value or axis

An example is a function that uses all numbers on the x axis is All Real Numbers

Thanks! I worked on some problems... I got it kinda figured out so far, but you summed it up very well!
