Math Problem Statement
Solution
The question in the image is asking to find the image (reflection) of the parabola function after being rotated counterclockwise by 90° around the point .
Steps to solve:
-
Convert the function to parametric form: To rotate the graph, we must treat the function's points as coordinates that will be rotated around .
-
Rotation formula: To rotate a point around a point by 90° counterclockwise, the transformed point is given by:
-
Apply the transformation to the equation: For each point on the parabola, we substitute and apply the transformation.
Would you like me to continue with detailed steps applying this transformation to the function? Also, let me know if you have any questions!
Here are 5 related questions:
- How is the rotation of a point around an arbitrary point calculated in general?
- What happens to the symmetry of a parabola when it is rotated?
- Can this rotation be generalized for angles other than 90°?
- What are parametric equations, and how are they used in geometric transformations?
- How do you calculate the new vertex of a parabola after a rotation?
Tip: Always ensure that points are shifted to the origin first before applying a rotation transformation, especially for rotations around points other than the origin!
