Answer:  y = -(x + 2)²

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(bx - h)² + k    where

  • a: vertical stretch (if negative it is a reflection across x-axis)
  • b: horizontal stretch (if negative it is a reflection across y-axis)
  • h: horizontal shift (negative is left and positive is right)
  • k: vertical shift (negative is down and positive is up)
  • (h, k): vertex of the function

Given: reflection over x-axis → a = -1,   two units left → c = -2

Input those values into the equation:  y = -(x - (-2))²

                                              simplify:   y = -(x + 2)²
