Answer: Hyperbola , parabola, circle and ellipse
Step-by-step explanation:
A line always represents the graph of linear equation.
Hyperbola , parabola, circle and ellipse are four conic sections
Conic sections are known as quadratic relations because their equations are of second order but are not always functions.
For Example :-A conic section is a circle when the [tex]x^2[/tex] and [tex]y^2[/tex] terms have the same sign and equal coefficients. A circle is a quadratic relation (not a function).
Similarly ellipse and hyperbola is a quadratic relation.
A parabola has an equation that contains only one squared term and hence its a quadratic relation.
Therefore, the right answers are Hyperbola , parabola, circle and ellipse.
