Determine the equation for the graph of $f(x)=x^2$ that has been shifted up 4 units. The Parent Function is the simplest function with the defining characteristics of the family. If $|a|>1$, the point associated with a particular $x$-value shifts farther from the $x$–axis, so the graph appears to become narrower, and there is a vertical stretch. Algebra Unit 6: Graphing Quadratic Functions Notes 1 Day 1: Quadratic Transformations (H & K values) The parent function of a function is the simplest form of a function. A quadratic transformation relates two hypergeometric functions, with the variable in one a quadratic function of the variable in the other, possibly combined with a fractional linear transformation. But if $|a|<1$, the point associated with a particular $x$-value shifts closer to the $x$–axis, so the graph appears to become wider, but in fact there is a vertical compression. The standard form is useful for determining how the graph is transformed from the graph of $y={x}^{2}$. (credit: modification of work by Dan Meyer).
