Answer:
neither because A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.
Answer:
