Graph: two downward-opening parabolas/curves are shown, with one peak near (-2, 6) and a marked point near (-1, 3); position_hint: center
Can you make an equation in vertex form
1. **State the problem:**
We are given a parabola with vertex at $(-2, 6)$ and a point on the parabola at $(-1, 3)$. We want to find the equation of the parabola in vertex form.
2. **Recall the vertex form of a parabola:**
$$y = a(x - h)^2 + k$$
where $(h, k)$ is the vertex.
3. **Substitute the vertex:**
Here, $h = -2$ and $k = 6$, so
$$y = a(x + 2)^2 + 6$$
4. **Use the given point $(-1, 3)$ to find $a$:**
Substitute $x = -1$ and $y = 3$:
$$3 = a(-1 + 2)^2 + 6$$
$$3 = a(1)^2 + 6$$
$$3 = a + 6$$
5. **Solve for $a$:**
$$a = 3 - 6 = -3$$
6. **Write the final equation:**
$$y = -3(x + 2)^2 + 6$$
This is the equation of the parabola in vertex form that passes through the given points.
