Have you found yourself scratching your head over the complexities of Unit 9 Transformations homework 1? You're not alone! Many students encounter challenges when tackling this assignment. But fear not, because we're here to guide you through with the answer key that unlocks all the secrets. Let's dive in and unravel the mysteries together!
Understanding Transformations: A Brief Overview
Before delving into the specifics of homework 1, let's brush up on our understanding of transformations. In mathematics, transformations refer to changes made to a geometric shape or object. These changes can include translations, rotations, reflections, and dilations. Each transformation has its own set of rules and properties that govern how it affects the shape.
Homework 1: Exploring Basic Transformations
In Unit 9 homework 1, you'll encounter a series of questions that test your comprehension of basic transformations. These questions may involve identifying the type of transformation applied to a given shape, determining the coordinates of a transformed shape, or performing transformations based on given instructions.
Answer Key: Cracking the Code
Now, let's get to the heart of the matter – the answer key! Below, you'll find detailed explanations for each question in homework 1:
1. Translation
Question: Given the point A(2, 3), perform a translation of (x, y) → (x + 4, y - 2).
Answer: To translate point A(2, 3) by (4, -2), add 4 to the x-coordinate and subtract 2 from the y-coordinate. Therefore, the new coordinates of point A after translation are (6, 1).
2. Rotation
Question: Rotate triangle ABC 90 degrees counterclockwise about the origin.
Answer: To rotate a point (x, y) 90 degrees counterclockwise about the origin, swap the x and y coordinates and change the sign of the new x-coordinate. Therefore, the new coordinates of triangle ABC after rotation are A'(-3, 1), B'(-1, -2), and C'(2, -3).
3. Reflection
Question: Reflect point P(4, -5) over the x-axis.
Answer: To reflect a point over the x-axis, negate the y-coordinate. Therefore, the image of point P(4, -5) after reflection is P'(4, 5).
4. Dilation
Question: Dilate triangle XYZ with a scale factor of 2.
Answer: To dilate a point (x, y) by a scale factor of 2, multiply both the x and y coordinates by 2. Therefore, the new coordinates of triangle XYZ after dilation are X'(4, 6), Y'(0, 4), and Z'(-2, 0).
Conclusion: Mastering Transformations
Congratulations! By utilizing this answer key, you've conquered the challenges presented in Unit 9 Transformations homework 1. Remember, practice makes perfect, so don't hesitate to revisit these concepts and continue honing your skills. With dedication and perseverance, you'll become a transformation master in no time!

We can think graphs of absolute value and quadratic functions as transformations of the parent functions |x| and x². Importantly, we can extend this idea to include transformations of any function whatsoever! This fascinating concept allows us to graph many other types of functions, like square/cube root, exponential and logarithmic functions.
