The U-shaped graph of a quadratic function is called a parabola. The simplest shift is a vertical shift, moving the graph up or down, because this transformation involves adding a positive or negative constant to the function.In other words, we add the same constant to the output value of the function regardless of the input. g(x) = x - 2 → The constant k is not grouped with x, so k affects the , or . The transformation of the parent function is shown in blue. When a function is shifted, stretched (or compressed), or flipped in any way from its " parent function ", it is said to be transformed, and is a transformation of a function. It is a shift down (or vertical translation down) of 1 unit. In this section we are going to see how knowledge of some fairly simple graphs can help us graph some more complicated graphs. Now that we have two transformations, we can combine them. A reflection on the x-axis is made on a function by multiplying the parent function by a negative.
