a) Domain D of function E and what it represents. b) Range R of function E a

a) Given: The following table represents a function E that gives the highest elevation in each of the seven continents.
$\begin{array}{|cc|}\hline Continent& Elevation(Feet)\\ Asia& 29,028\\ S.Ameriva& 22,834\\ N.America& 20,320\\ Africa& 19,340\\ Europe& 18,510\\ Antarctica& 16,056\\ Australia& 73,10\\ \hline\end{array}$
Conclusion:
We know that domain is obtained by writing a set of all the possible inputs together. Since inputs of this function are all seven continents, thus, domain of the given function E is ${\displaystyle D=\{Asia,S.America,N.America,A\mathfrak{i}ca,Europe,Antarctica,Australia\}}$
Domain represents the set of all possible inputs of the function.
b) Given: The following table represents a function E that gives the highest elevation in each of the seven continents.
$\begin{array}{|cc|}\hline Continent& Elevation(Feet)\\ Asia& 29,028\\ S.Ameriva& 22,834\\ N.America& 20,320\\ Africa& 19,340\\ Europe& 18,510\\ Antarctica& 16,056\\ Australia& 73,10\\ \hline\end{array}$
Conclusion: We know that range is obtained by writing a set of all the possible outcomes together. Since outputs of this function are the highest elevations in each of the seven continents, thus, range of the given function E is
${\displaystyle D=\{Asia,S.America,N.America,A\mathfrak{i}ca,Europe,Antarctica,Australia\}}$
c) Given: The following table represents a function E that gives the highest elevation in each of the seven continents.
$\begin{array}{|cc|}\hline Continent& Elevation(Feet)\\ Asia& 29,028\\ S.Ameriva& 22,834\\ N.America& 20,320\\ Africa& 19,340\\ Europe& 18,510\\ Antarctica& 16,056\\ Australia& 73,10\\ \hline\end{array}$
Conclusion: While writing domain or range, we list the repeated elements only once. Thus, the elevation should be listed only once in the range if it is repeated.
