Find the domain and Range of
1) F(x)=2x; or y=2x The domain x will be all real numbers so the range F(x) is also the real numbers.
2)f(x)=Capitals of states in the US
Domain of f(x) or x is the set of 50 states and the range are the set of Capitals so
F(Georgia)=Atlanta And so on, for each state there is one and only one Capital city.
3) F(x)= cities with a baseball team The domain is the baseball team and the range is the city where the team plays home games.
F(cubs)=Chicago and F(tigers)=Detroit also F(white sox)=Chicago and so on for each team you have a city
