1. **State the problem:** We have two quadratic functions:
$$f(x) = a(x - 3)^2 + 5$$
$$g(x) = a(x + 2)^2 - 1$$
We want to describe how the vertex of $g(x)$ is shifted relative to the vertex of $f(x)$ in terms of units left/right and up/down.
2. **Identify the vertices:**
The vertex form of a quadratic function is:
$$y = a(x - h)^2 + k$$
where $(h, k)$ is the vertex.
- For $f(x)$, the vertex is at $(3, 5)$.
- For $g(x)$, rewrite $g(x)$ as $a(x - (-2))^2 - 1$, so the vertex is at $(-2, -1)$.
3. **Calculate horizontal shift:**
Horizontal shift = $x$-coordinate of $g$ vertex $-$ $x$-coordinate of $f$ vertex
$$-2 - 3 = -5$$
A negative value means a shift to the left by 5 units.
4. **Calculate vertical shift:**
Vertical shift = $y$-coordinate of $g$ vertex $-$ $y$-coordinate of $f$ vertex
$$-1 - 5 = -6$$
A negative value means a shift down by 6 units.
5. **Final answer:**
Compared to the graph of $f(x)$, the vertex for the graph of $g(x)$ has been shifted **5 units to the left**, and **6 units down**.
