It's a parabola with vertex (3,0)
which is y=(x-3)^2
for (1,4) 4=(1-3)^2 = 2^2 (You probably made a typo and meant (1,4) not (0,4) the 1 and 0 are close on the keyboard and maybe you punched the wrong one)
for (4,1) 1 = (4-3)^2 = 1^2
It's the parabola y=x^2 shifted to the right 3 units
(2,1) and (5,4) are also on the parabola y=(x-3)^2
for (2,1) 1=(2-3)^2 = 1^2
for (5,4) 4=(5-3)^2 = 2^2
the points that were (1,4) and (4,1) become (2,1) and (5,4) if you increase x by one and find the corresponding y values on the parabola
A) is probably the answer you want
although usually this type of problem involves a shift in the parabola, right, left, up or down. But this is a movement along the parabola without any shift in the parabola itself.
