The second photo is the correct graph.
In order to have a function we can't repeat any value in the x, therefore in order to have a function represented in the table the question mark must be 2
The solution to given quadratic equation is x = -0.3851 or x = 10.3851
<em><u>Solution:</u></em>
Given equation is:

To find: solve by quadratic equation formula

Using the above formula,

<u><em>Substituting the values of a = -4 ; b = 40 ; c = 16 in above quadratic formula we get,</em></u>

Thus the solution to given quadratic equation is x = - 0.3851 or x = 10.3851
