Parabola Transformation 54C232
1. **Problem:** Determine the equation of the parabola after applying the transformation $(x,y) \to (x+4, \frac{1}{4}y)$ to the graph of $y = x^2$.
2. **Original equation:** $y = x^2$
3. **Transformation explanation:** The transformation changes the $x$-coordinate to $x+4$ and the $y$-coordinate to $\frac{1}{4}y$. This means the new parabola's points $(X,Y)$ relate to the original points $(x,y)$ by:
$$X = x + 4, \quad Y = \frac{1}{4} y$$
4. **Express original $x$ and $y$ in terms of $X$ and $Y$:**
$$x = X - 4, \quad y = 4Y$$
5. **Substitute into original equation:**
$$y = x^2 \implies 4Y = (X - 4)^2$$
6. **Solve for $Y$:**
$$Y = \frac{(X - 4)^2}{4}$$
7. **Rename variables for clarity:**
Let $x = X$ and $y = Y$ for the transformed graph, so the equation is:
$$y = \frac{(x - 4)^2}{4}$$
**Final answer:**
$$\boxed{y = \frac{(x - 4)^2}{4}}$$
This is the equation of the parabola after the given transformation.
