Section 2.7 – A Preview of Transformations • Objective: • Identify the transformation(s) from one function to another • Standard: • 2.8.11.Q. Represent functional relationships in tables, charts, and graphs
Parent Functions • Quadratic Function • f(x) = x2 • Absolute Value Function • f(x) = lxl • Radical Function • f(x) = √x
Vertical Translations • Consider the Quadratic parent function • How can we move this graph 2 spaces up? • How about 4 spaces down?
Horizontal Translations • Consider the Absolute Value parent function • How can we move this graph 3 spaces to the left? • How about 5 spaces to the right?
Vertical Stretch and Compression • Consider the Radical parent function • How can we vertically stretch this graph by a factor of 4? • How can we vertically compress this graph by a factor of ½ ?
Horizontal Stretch and Compression • Lets consider the Quadratic parent function. • How can we horizontally stretch this graph by a factor of 4? • How can we horizontally compress this graph by a factor of ⅓?
Reflections • Let’s consider the Radical parent function • How can we Vertically Reflect (across the x-axis) this graph? • How can we Horizontally Reflect (across the y-axis) this graph?
Identify each transformation from the parent function 1. Vertical Reflection, Horizontal Translation 4, & Vertical Translation 3 2. 3. The graph of vertically stretched by a factor of 2 and translated 1 unit to the right. 4. The graph of reflected across the x-axis, stretched horizontally by a factor of 5 and translated up 4 Combined Transformations Horizontal Reflection & Horizontal Compression by a factor of ¼ Write the function for each graph described.
