Math Problem Statement
Solution
The graph shown is of the function , which is a standard parabola with its vertex at the origin .
The task is to translate this graph to match the equation . Here's how the transformation happens:
-
Horizontal Translation: The term indicates a horizontal shift. Specifically, the graph is shifted 4 units to the left. In general, shifts the graph units horizontally, and since , the graph moves left by 4 units.
-
Vertical Translation: The outside the square indicates a vertical shift 2 units up. This means the graph moves upwards by 2 units.
So, the vertex of the new parabola will be at instead of .
Steps to graph the translation:
- Shift the entire graph of 4 units to the left.
- Then, shift the graph 2 units upwards.
The result is a new parabola with vertex , which opens upwards like the original graph of , but is now translated.

- How would the graph change if the equation was ?
- What does the general form represent geometrically?
- How would the shape of the parabola change if the equation had a coefficient, like ?
- How does a vertical stretch or compression affect the vertex form of a parabola?
Tip: Always pay attention to signs inside and outside the squared term to understand horizontal and vertical shifts correctly!
