Answer
Translating by $3$ to the right the graph of $y=x^2$ we get the graph of $y=(x-3)^2$.
Work Step by Step
We can start with the graph of $y=x^2$ and to get the graph of $y=(x-3)^2$ from it we translate it to the right by $3$ (move every point of it rightwards by $3$) as is done on the figure below.
