The document discusses function notation and transformations of functions. It provides examples of writing quadratic, cubic, and rational functions in function notation. It also demonstrates how functions are translated vertically by adding or subtracting a number from the original function. Translating a function f(x) by a results in the new function f(x)+a or f(x)-a.

Pre-calculus 1, 2 and Calculus I (exam notes)William Faber
Notes I typed using Microsoft Word for pre-calculus and calculus exams. Most of the images were also created by me. I shared them with other students in my class to increase their chance of success as well. Upon completion of the courses I donated them to the math center to help other math students.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

30. Translating functions
Given that f(𝒙) = 𝒙𝟐
𝒚 = f(𝟒) + 2 = (𝟒)𝟐 + 2 = 18

Now let 𝒚 = f(𝒙 + 𝟐)
What is 𝒚 if 𝒙 = 4?

What is 𝒚 if 𝒙 = 4?
𝒚 = f(𝟒 + 𝟐) = (𝟔)𝟐 = 36

32. Translating functions
Given that f(𝒙) = 𝒙𝟐
𝒚 = f(𝟒) + 2 = (𝟒)𝟐 + 2 = 18
Let 𝒚 = f(𝒙) + 2

What is 𝒚 if 𝒙 = 4?
𝒚 = f(𝟒 + 𝟐) = (𝟔)𝟐 = 36
