1. **State the problem:**
We are given a parabola with specific points and asked to identify its x-intercepts, y-intercept, vertex, and axis of symmetry.
2. **Identify the x-intercepts:**
The x-intercepts are the points where the parabola crosses the x-axis, meaning the y-value is 0.
From the problem, these points are given as $(-2, 0)$ and $(5, 0)$.
3. **Identify the y-intercept:**
The y-intercept is where the parabola crosses the y-axis, meaning the x-value is 0.
We can find it by using the vertex form or by finding the equation of the parabola and evaluating at $x=0$.
4. **Find the equation of the parabola:**
The vertex form of a parabola is:
$$y = a(x - h)^2 + k$$
where $(h, k)$ is the vertex.
Given vertex $(1.5, -9)$, the equation is:
$$y = a(x - 1.5)^2 - 9$$
5. **Use an x-intercept to find $a$:**
Using point $(-2, 0)$:
$$0 = a(-2 - 1.5)^2 - 9$$
$$0 = a(-3.5)^2 - 9$$
$$0 = a(12.25) - 9$$
$$a(12.25) = 9$$
$$a = \frac{9}{12.25} = \frac{9}{12.25}$$
6. **Simplify $a$:**
$$a = \frac{9}{12.25} = \frac{9}{\cancel{12.25}} = 0.7347$$ (approximate)
7. **Find the y-intercept by evaluating at $x=0$:**
$$y = 0.7347(0 - 1.5)^2 - 9$$
$$y = 0.7347(2.25) - 9$$
$$y = 1.653 - 9 = -7.347$$
So the y-intercept is approximately $(0, -7.35)$.
8. **Axis of symmetry:**
The axis of symmetry is the vertical line through the vertex:
$$x = 1.5$$
**Final answers:**
- X-Intercepts: $(-2, 0)$ and $(5, 0)$
- Y-Intercept: $(0, -7.35)$
- Vertex: $(1.5, -9)$
- Axis of Symmetry: $x = 1.5$
