WebGraphing Quadratic Functions – Example 1: Sketch the graph of \ (y= (x+1)^2-2\). Solution: First, recall that a Quadratic function in vertex form is \ (y=a (x – h)^2+k\) where \ ( (h,k)\) is the vertex of the function. The vertex of \ (y= (x+1)^2-2\) is \ ( (-1,-2)\). Substitute zero for \ (x\) and solve for \ (y\). \ (y= (0+1)^2-2=-1\).

WebWe can think graphs of absolute value and quadratic functions as transformations of the parent functions x and x². Importantly, we can extend this idea to include transformations of any function whatsoever! This fascinating concept allows us to graph many other types of functions, like square/cube root, exponential and logarithmic functions.
