"Graphing a quadratic function using transformations" (If the focus is on visualizing the change from a basic function like y=x^2 to a new one like y=(x-h)^2 k.) ​This concept usually refers to graphical transformations (translation, reflection, stretch/compression) of the parent function y = x^2 to obtain the graph of a general quadratic function y = a(x-h)^2 k. | Bnedine Bnedine
