The graph of y = f(x) is a parabola whose vertex is at (2,-1). The graph of y = f(x + 3) is also a parabola. Where is the vertex of the graph of y = f(x + 3). Write your answer as an ordered pair.
+1224 y = f(x+3) is the same as the graph of y = f(x), just shifted to the left 3 units. So, the vertex of y = f(x+3) is (-1, -1).
