The fuel tank of a certain airplane can hold up to 300 gallons of fuel. Let W be the total weight of the airplane (in pounds). L
et F be the total amount of fuel in its tank (in gallons). Suppose that W=6F+4000 gives W as a function of F . Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.
Yes it is true! it is true because two different numbers go to the same number, if it was false it would have to be the one number to two different numbers.
