f(x) = (x + 3)^2

Translation just means shift or slide. To show a LEFT shift in the equation, go in close to the x, inside the parenthesis with the x, for LEFT shift, insert +3.
Left and right shifts might be the opposite of what you may think. Minus a number shifts right and plus a number shifts left.
For the graph, see image. The answer is the green curve.
