If the domain of the function F = (x, y) is {1, 2, 3}, what is the range? {1, 2, 3} {1, 3, 5} {2, 5/2, 3}

Question

If the domain of the function F = 2x + y = 7 is {1, 2, 3}, what is the range?

{1, 2, 3}
{1, 3, 5}
{2, 5/2, 3}

Answer 1

The range is equal to {1, 3, 5}. You can find this by graphing the function 2x + y =7.
