The Deep Dive

To graph \( g(x) = (x - 4)^2 \), start with the basic parabola of \( f(x) = x^2 \), which opens upwards and has its vertex at the origin (0, 0). The expression \( (x - 4) \) indicates a horizontal shift of the graph 4 units to the right. So, instead of the vertex being at (0, 0), it moves to (4, 0). To visualize this transformation, plot the new vertex at (4, 0) and still keep the parabola's shape intact. You can choose additional points for clarity, like (3, 1) and (5, 1), both reflecting symmetry about the vertex. Thus, the final graph will be an upward-opening parabola with its vertex at (4, 0). The exciting part of this transformation is how simple shifts can completely change the position of a graph without altering its fundamental characteristics! With just that horizontal move to the right, you've created a new function with a different vertex while still preserving the ever-familiar parabolic form.
