A quadrilateral with only 2 right angles could be a trapezoid so Balavan is wrong. Denna is right because if 3 angles are right angles the the fourth angle must also be a right angle and has to be a square or rectangle.
Narrowing it down it's either a or c because the other 2 choices open downward (negative a).
Graphing the 2 parabolas choice c is narrower.
c

1/2 is a rational number.
Step-by-step explanation:
A rational number can be expressed as a ratio of two numbers. 1/2 is a ratio.
It is also a real number, however you do not list that as a category, so from what you listed, it is only a rational number.
Since the vertex is at (-3, 6), the equation is given by
y = a(x + 3) + 6
Therefore, option A is the correct answer.
