The reference equation, or graph, is a parabola corresponding to f(x) = x^2, with the minimum at (0,0). For convenience, we will call this f(z) = z^2, so as not to confuse the two variables, and handle each transformation as a modification to the function f(z). (See Figure 1 (a))
The relevant transformations in this case are:
z = x-7 shifts the graph 7 to the right, because to give the equivalent value for f(x), and by ...
This shows how to plot a function using transformations.
