a.
Explanation of Solution
Given information:
The term ‘parabola’.
An open plane curve which is symmetrical in nature and is formed by the intersection of a cone with a plane parallel to its side is known as parabola. When a quadratic function is graphed, it forms a parabola, a u-shaped curve that has to meet certain technical mathematical requirements. A narrow curve at the end of an oval can be imagined as a parabola.
