    { (0,1), (1,2), (2,3), (3,4) } { (0,4), (1,6), (3,10), (5,14) }

    Step-by-step explanation:

    When x-differences are the same, y-differences will be the same for a linear function. When they are not the same, they will be proportional for a linear function.

    { (0,1), (1,2), (2,3), (3,4) } - x-differences are all the same; y-differences are all 1 (linear, y=x+1)

    { (0,0), (1,1), (2,4), (3,9) } - x-differences are all the same; y-differences increase (this is a quadratic function: y=x^2)

    { (1,1), (2,8), (3,27), (4,64) } - x-differences are all the same; y-differences increase (this is a cubic function: y=x^3)

    { (0,4), (1,6), (3,10), (5,14) } - x-differences are 1, 2, 2; y-differences are 2, 4, 4, so are proportional to (double) the x-differences (linear; y=2x+4)
