Transformations of quadratic functions
Related Concepts: Transformations of functions: Horizontal translations, Transformations of functions: Vertical translations, Reflection across the y-axis: y=f(−x), Reflection across the x-axis: y=−f(x)
Lessons
- 1.Reflection in the x-axis
Reflect a quadratic function in the x-axis:a)Sketch the following functions on the same set of coordinate axes:
y=x2 VS. −y=x2b)Compared to the graph of y=x2, the graph of −y=x2 is a reflection in the _______________ . - 2.Compared y=x2 to basic quadratic function:
i) describe every step of transformations
ii) use transformation concepts to sketch the functiona)y=2(x−3)2−8b)y=−31(x+5)2+4
