সমীকরণ $x^2+y+3=0$ নিচের কোনটি নির্দেশ করে?

The given equation is in the format of a quadratic equation, which can be written as:

x² + y + 3 = 0

This type of equation generally represents a parabolic shape when graphed. A parabola is characterized by its U-shaped curve, which is typical of quadratic functions. In this case, since the variable x is squared and there is a linear term involving y, it confirms that it describes a parabola.

Here’s a brief description of the options for clarity:

    
• বৃত্ত (Circle): A set of points that are all at the same distance from a central point.
    
• উপবৃত্ত (Ellipse): An elongated circle or oval shape.
    
• প্যারোবোলা (Parabola): The shape defined by a quadratic equation, like the one given.
    
• মৌলিক (Fundamental): Relating to the basic or foundational aspects, not specifically relevant to the shape types here.

Therefore, selecting প্যারোবোলা is correct since it accurately describes the form represented by the equation.
