Assuming the x-y plane, the domain is usually considered to be the span of x values covered by a function and the range is the span of y values covered by the same function


Example :   Look at the graph of  y  = (x - 6)(x - 3) (x + 3) here :





"x"  can take on any value.......so the domain is (-infinity, infinity)

And "y"  can also take on any value....so the range is (-infinity, infinity)




cool cool cool
