Final answer:
The function y=(x-2)² describes a parabola with a vertex at (2, 0) and opens upwards. To plot it, calculate y for various x values and then graph these plotting data pairs.
Step-by-step explanation:
The given function y=(x-2)² can be described as a parabola that is symmetrical about the vertical line x=2. This is evident from the squared term, indicating it is a quadratic function. To plot this function, one might create a table of plotting data pairs for different values of x, calculate the corresponding y values, and then plot these points on a coordinate plane. An example of plotting data pairs for various x values could start with x = 0, 1, 2, 3, and 4, to observe the symmetry and shape of the parabola. The vertex of the parabola is at (2, 0) because the equation is in vertex form. Generally, this function will generate a graph that opens upwards, since the coefficient of the squared term is positive.
