Answer: <
im sorry if this is wrong im not entirely sure :(

The given equation is a Quadratic equation, so it's graph must be a parabola, and the Coefficient of x² is positive that means the parabola must have an opening upward.
And 2 is added to the ideal equation, so the parabola must have shift 2 units up from x - axis.
From the above information, we can easily conclude that the Correct representation is done in graph 4
Heres your answer,
Point L.
The compatible number is 7 (seven)
[-8,8] because both points are closed points.
