The maximum point of (-2,5) is a vertex.
Because the vertex is a maximum, the parabola faces downward.
Therefore the leading coefficient of the quadratic term is negative.
The standard form of the parabola that represents the quadratic function is
y = -(x + 2)² + 5
The graph confirms that the equation is correct.
Answer: y = -(x + 2)² + 5
