the number of miles of a car can run depends on the gallon of gasoline in the tank ? what is the best situation to describe this ?

Question

a the range of function ? 

b a relation that is not a function 

c a relation that is a function 

d the domain of a function ? 

Answer 1

This is a direct proportion since the number of miles able to be driven varies directly with the number of gallons of gas in the tank.

y=kx....   In this case Distance=(miles/gallon)(gallons)

 

This is a relation that is a function.
