Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
The list contains three points that lie on the graph of the reflection is (-49, 7), (-18, 9), (-1, 1).
<h3>What is graph reflection?</h3>
The graph of any function when mirrored on the same plane.
Given the graph of f(x)=√x is reflected over the y-axis. Use the graphing calculator to graph this reflection.
The points which can satisfy the reflection of the graph is (-49, 7), (-18, 9), (-1, 1).
Thus, the fourth option is correct.

Pythagorean theorem - a^2 + b^2 = c^2
2^2+3^2 = d^2
d^2 = 13
d= square root of 13
I think the answer is 6. ABC, ACB, BAC, BCA, CAB, and CBA.
