Example: Graphing
To graph a quadratic function involving multiple transformations, such as , identify the horizontal shift constant and the vertical shift constant . Comparing it to the standard transformation form , rewrite the function as . This shows that and . A negative indicates a horizontal shift to the left by unit, while a negative indicates a vertical shift downward by units. By starting with the basic parabola , shifting it left unit, and then down units, you produce the final graph of .
