Which of the following digits could replace the ? in the tens place to make this statement true 63? 5 rounds to the 6370 if we round to the nearest ten

?=6 so the number would be 6365 but sorry if it's wrong :/

The discriminant tells us how many real solutions there are. Since the parabola doesn't have any x-intercepts, the discriminant is less than zero, and therefore is answer A.

If a discriminant is:
>0, there are 2 x-intercepts
=0, there is 1 x-intercept
<0, there are no x-intercepts
