(a)Determine the domain D of function E and explain what it represents
(b)Determine the range R of function E and explain what it represents.
(c)Suppose two continents had the same highest elevations. How many time would you list this elevation in range R?

Explanation / Answer
(a). Here, the independent variable is a continent so that the seven continents constitute the domain D of function E.
(b). The independent variable is the highest elevation located in a continent so that the highest elevation located in each of the seven continents constitute the range R of function E.
( c). If two continents had the same highest elevations, this would still be listed as only one elevation in range R.
