You can put this solution on YOUR website! Domain is the set of the independent variable, usually x,,
.
while Range is the set of the dependent variable, usually y
.
Physically Domain might be time while Range is Weight, for a diet log
.
or Domain might be elapsed time vs Range , distance, for a travel log,
.
Usually Domain and Range are expressed as, "all Real Numbers"

Exceptions occur when the value of the function, dependent variable, is

UNDEFINED,(denominator is zero),or COMPLEX (square root of a negative number)
