Answer

Answer:

$y=2(x+2)^2 + 5$

Explanation:

Step1: Recall vertex form

The vertex form of a quadratic function is $y=a(x-h)^2+k$, where $(h,k)$ is the vertex.

Step2: Identify vertex from graph

The vertex of the parabola is $(-2, 5)$, so $h=-2$, $k=5$.

Step3: Substitute vertex into form

Substitute $h=-2$, $k=5$ into the vertex form: $y=a(x-(-2))^2+5 = a(x+2)^2+5$.

Step4: Confirm stretch factor

The parabola opens upwards and has a vertical stretch; the only matching option with this vertex is $y=2(x+2)^2 + 5$.
