Final answer:
The function f(x) = x^2 shifted to the right by 3 units is represented as f(x) = (x - 3)^2.
Step-by-step explanation:
To move the graph of the function f(x) = x^2 to the right by 3 units, you need to adjust the input variable x. To achieve this shift, you must subtract 3 from x before it is squared in the function. Therefore, the new function after the graph has been shifted to the right by 3 units will be f(x) = (x - 3)^2. This is because each x value on the graph of y = x^2 will be increased by 3 to reach its new position on the graph of f(x).
