A vertical shift affects only the y-value of the vertex, not the x-value. The vertex of a parabola or any graph shifts up or down based on the vertical shift, but the x-coordinate remains unchanged.

Would you like more details or have any questions?

Here are some related questions to explore:

1. What is the effect of a horizontal shift on the vertex of a parabola?
2. How does a vertical stretch or compression affect the vertex?
3. How does adding a constant to a quadratic equation affect the graph?
4. Can a reflection over the x-axis or y-axis change the vertex position?
5. How do you find the vertex of a parabola given its equation?

Tip: The formula for the vertex of a quadratic equation $y = ax^2 + bx + c$ is $\left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)$, where the x-value depends on the coefficients of the quadratic, and the y-value depends on vertical shifts.
