y = 2 {x}^{2}  - 3

\huge\underline\mathtt\colorbox{cyan}{Explanation thing:}

Using hit and trial, you van find it pretty easily-

  • Putting x=0, we get y=-3
  • Putting x=1, we get y=-1
  • Putting x=2, we get y=5

You can try it for yourself as well, for me, I couldn't find any other option appropriate.
