How to find domain and range from co-ordinate pairs?
- If (x,y) is a pair x is domain,y is range.
Now starting and ending point on x axis
- (-2,0)
- (4,0)
Hence
[tex]\ \ \sf\longmapsto D_f=\{-2,4\}[/tex]
Starting and ending point on y axis
- (0,0)
- (0,-3)
Hence
[tex]\ \ \sf\longmapsto R_f=\{0,-3\}[/tex]
