Ineed trying to figure out what is the domain as well as the range and determine if it's a function or not

Domain is the x values
so assuming each grid is 1 unit
it goes from -4 to 5
so domain is [-4,5]

range is from lowest to highest
that is from 0 to 4
range is [0,4]

it is nof a function because we can draw a vertaical line and go thorugh the graph twice

domain: [-4,5]
range: [0,4]
not a function

32.68 the is the !
