Answer: f(x) = x²

Step-by-step explanation:

The vertex form of a quadratic equation is: f(x) = a(x - h)² + k   where;

  • |a| is the vertical stretch
  • -a is a reflection across the x-axis
  • (h, k) is the vertex

The parent function is where a = 1 and the vertex is at the origin (h, k) = (0, 0)

→ f(x) = 1(x - 0)² + 0

⇒ f(x) = x²
