Choose the function that represents the data in the table.

viva [34]

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

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

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.
