In mathematics, graph transformations are a fundamental concept that helps students understand how functions behave and relate to each other. The transformation of graphs involves changing the position, shape, or size of a graph. In this article, we will explore the concept of graph transformations, discuss various types of transformations, and provide a comprehensive exercise to help students practice and reinforce their understanding.

Sample DSE‑style Questions
- The graph of y = 1/x is transformed to y = a/(x−2) + 3. Given the vertical and horizontal asymptotes, identify a and sketch for a = −2.
- A function f has zeros at x=−2,0,3. Describe the zeros after transformation g(x)=−2 f(0.5(x+4)) + 1.
- The curve y = ln x is shifted and stretched to y = 2 ln(3(x−1)) + 4. State domain and vertical asymptote.
The most effective way to organize transformations is by whether the change happens inside the brackets (affecting ) or outside (affecting Outside : Changes are vertical and follow your intuition (e.g., +kpositive k moves it up). Inside The graph of y = 1/x is transformed to y = a/(x−2) + 3
