How is the graph of the function y = (x + 3)^2 obtained from the basic parabola y = x^2?

Answer and explanation

Correct answer: By shifting 3 units to the left

The graph of y = f(x + 3) is obtained by shifting the graph of y = f(x) 3 units to the left. Here f(x) = x^2, so the vertex of y = (x + 3)^2 is (-3, 0). A rightward shift is incorrect because a positive number added inside the function causes a horizontal shift to the left. Exam tip: f(x - a) shifts a graph a units right, while f(x + a) shifts it a units left.
