Form or written form of the relationship that defines a function and that highlights the parameters that transform the basic form of the function.
The standard form is a parametric form of a function rule in which the parameters characterize a transformation of the function’s graph.
The standard form that defines a second-degree polynomial function is:
f(x) = a(b(x – h))² + k
where the parameters h and k characterize the horizontal translation and the vertical translation, respectively, of the graph of the function associated with its basic form, and the parameters a and b characterize a vertical dilation and a horizontal dilation, respectively, of the graph associated with the basic form.
