#### Answer

$y=4x^2$

#### Work Step by Step

Using the first coordinate, we see that the y-intercept is $(0,0).$ Then, notice that the y-coordinates of the next four terms when divided by $4$ equal the square of the x values. Using that we can write the rule $y=4x^2,$ which satisfies all of the points given.
