Question

Which relation represents f(x) = 2x - 5?

{(0,-5), (1, -3), (2, 1), (3, 1))
{(0,-5), (1,3), (2, -1), (3, 1))
{(0,-5), (1, -3), (2, -1), (3, 1);
{(0,5), (1, -3), (2, -1), (3, 1)}

Answer 1

{(0,-5), (1, -3), (2, -1), (3, 1)

Explanation:

If you plug in 1 for x you get f(x)=2(1)-5 which equals 2-5=-3

You would repeat these steps just going up by one number every time
