In the realm of algebra, the transformations of quadratic functions provide a powerful toolkit for manipulating and analyzing quadratic equations. In this comprehensive guide, we will explore the intricacies of transforming quadratic functions, delve into various types of transformations, and present a set of skills practice problems enriched with a detailed answer key.
Unveiling the Art of Quadratic Function Transformations
Transformations offer a way to modify the shape, position, and orientation of quadratic functions, providing insights into their behavior.
Skill 1: Basic Transformations
Basic transformations include shifts, stretches, and reflections. Shifting a quadratic function horizontally or vertically alters its position, while stretching or compressing it modifies its width.
Skill 2: Combining Transformations
Combining transformations allows you to perform multiple changes to a quadratic function. Sequencing these transformations leads to a refined understanding of their effects.
Solving Skills Practice Problems with Quadratic Function Transformations
Let’s apply our understanding to skills practice problems:
- Given the quadratic function f(x) = x², perform a horizontal shift 3 units to the right and a vertical stretch by a factor of 2. Write the transformed function.
Answer: The transformed function is g(x) = 2(x – 3)².
- If h(x) = -2x² + 4x + 5, apply a reflection across the x-axis followed by a vertical compression by a factor of 0.5. Determine the transformed function.
Answer: The transformed function is j(x) = -1(x² – 2x – 5/2).
- Consider the quadratic function k(x) = (x – 1)² + 3. Perform a vertical shift upward by 4 units and a horizontal compression by a factor of 0.8. Write the transformed function.
Answer: The transformed function is m(x) = (0.8x – 1)² + 7.
