Math Problem Statement
Solution
The question is asking how the graph of the quadratic function compares to the graph of its parent function .
To analyze this, let's break it down:
1. Parent Function:
The parent function is a basic parabola, opening upwards with its vertex at the origin .
2. Transformations of :
The function can be rewritten in vertex form to better understand its graph. To do this, we complete the square:
- Start with .
- Complete the square by taking half of the coefficient of (which is 4), squaring it, and adding and subtracting that value inside the equation:
Now the function is in vertex form: .
3. Comparison:
- Shift: The graph of is shifted left by 2 units and up by 6 units compared to the parent function .
- Same Shape: Since the coefficient of is still 1, the parabola opens upward and has the same width as the parent function.
- Vertex: The vertex of is at , while the vertex of is at .
In summary, the graph of is the same shape as , but shifted 2 units to the left and 6 units up.
