1. **State the problem:** Find the x- and y-intercepts of the parabola given by the equation $$y = 4x^2 - 12x + 9$$.
2. **Recall the definitions:**
- The **x-intercepts** occur where $$y = 0$$.
- The **y-intercept** occurs where $$x = 0$$.
3. **Find the y-intercept:**
Substitute $$x = 0$$ into the equation:
$$y = 4(0)^2 - 12(0) + 9 = 9$$
So, the y-intercept is at the point $$(0, 9)$$.
4. **Find the x-intercepts:**
Set $$y = 0$$ and solve for $$x$$:
$$0 = 4x^2 - 12x + 9$$
This is a quadratic equation. Use the quadratic formula:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $$a = 4$$, $$b = -12$$, and $$c = 9$$.
Calculate the discriminant:
$$\Delta = b^2 - 4ac = (-12)^2 - 4(4)(9) = 144 - 144 = 0$$
Since the discriminant is zero, there is one real repeated root:
$$x = \frac{-(-12)}{2 \times 4} = \frac{12}{8} = \frac{3}{2}$$
So, the x-intercept is at the point $$\left(\frac{3}{2}, 0\right)$$.
**Final answer:**
- x-intercept: $$\left(\frac{3}{2}, 0\right)$$
- y-intercept: $$(0, 9)$$
