Answer

Both are solutions

Work Step by Step

We are given that $y=2x^{2}$. In order to see whether each ordered pair is a solution of the given equation, we can plug in the ordered pair to the equation. For (1,2): $2\times1^{2}=2\times1=2$ So, (1,2) is a solution. For (3,18): $2\times3^{2}=2\times9=18$ So, (3,18) is a solution.
