1. **State the problem:** We are given a parabola with vertex at $(3,1)$ and need to find the x-intercepts $p$ and $q$ of the parabola.
2. **Identify the vertex form of the parabola:** The vertex form is $$y = a(x - h)^2 + k$$ where $(h,k)$ is the vertex. Here, $h=3$ and $k=1$, so
$$y = a(x - 3)^2 + 1.$$
3. **Find the value of $a$ using a point on the parabola:** From the graph, the parabola passes through $(0,8)$ (since at $x=0$, $y=8$). Substitute:
$$8 = a(0 - 3)^2 + 1 = a(9) + 1,$$
which gives
$$8 - 1 = 9a \\ 7 = 9a \\ a = \frac{7}{9}.$$
4. **Write the full equation:**
$$y = \frac{7}{9}(x - 3)^2 + 1.$$
5. **Find the x-intercepts $p$ and $q$ by setting $y=0$:**
$$0 = \frac{7}{9}(x - 3)^2 + 1 \\ \frac{7}{9}(x - 3)^2 = -1.$$
Since the right side is negative and the left side is always non-negative (square term), this equation has no real solutions. This contradicts the problem statement that $p$ and $q$ are x-intercepts.
6. **Re-examine the vertex y-value:** The vertex is at $(3,1)$, so the parabola opens upwards and the minimum y-value is 1, meaning it never crosses the x-axis. Therefore, there are no real x-intercepts $p$ and $q$.
7. **Conclusion:** The parabola does not intersect the x-axis, so $p$ and $q$ do not exist as real numbers.
**Final answer:** There are no real x-intercepts $p$ and $q$ for the given parabola.
