1. **Problem Statement:** Determine which statement about the graph of $$y = (3 - 2x)^2 + 1$$ is true.
2. **Rewrite the function:** Expand the square to get the quadratic in standard form.
$$y = (3 - 2x)^2 + 1 = (3 - 2x)(3 - 2x) + 1 = 9 - 12x + 4x^2 + 1$$
3. **Simplify:**
$$y = 4x^2 - 12x + 10$$
4. **Check the given options:**
- Option A: "The graph cuts the x-axis."
To check if the graph cuts the x-axis, solve $$y=0$$:
$$4x^2 - 12x + 10 = 0$$
Calculate the discriminant $$\Delta$$:
$$\Delta = (-12)^2 - 4 \times 4 \times 10 = 144 - 160 = -16$$
Since $$\Delta < 0$$, no real roots exist, so the graph does **not** cut the x-axis.
- Option B: "The graph opens downwards."
The coefficient of $$x^2$$ is $$4 > 0$$, so the parabola opens **upwards**, not downwards.
- Option C: "The axis of symmetry is $$x = 1.5$$."
The axis of symmetry for $$y = ax^2 + bx + c$$ is $$x = -\frac{b}{2a}$$.
Here, $$a=4$$ and $$b=-12$$, so:
$$x = -\frac{-12}{2 \times 4} = \frac{12}{8} = 1.5$$
This matches the option.
- Option D: "The y-intercept of the graph is 1."
The y-intercept is the value of $$y$$ when $$x=0$$:
$$y = 4(0)^2 - 12(0) + 10 = 10$$
So the y-intercept is 10, not 1.
5. **Conclusion:** The correct statement is **C. The axis of symmetry is $$x = 1.5$$**.
Final answer: **C**
