Q. What kind of transformation converts the graph of f(x)=5(x−9)2−2 into the graph of g(x)=5(x−9)2−8?Choices:(A) translation 6 units up(B) translation 6 units left(C) translation 6 units right(D) translation 6 units down
Identify Vertex: Identify the vertex of the function f(x). The function f(x)=5(x−9)2−2 is already in vertex form, where the vertex is given by (h,k). In this case, the vertex of f(x) is (9,−2).
Identify Vertex: Identify the vertex of the function g(x). The function g(x)=5(x−9)2−8 is also in vertex form, and the vertex is (h,k). Here, the vertex of g(x) is (9,−8).
Compare Vertices: Compare the vertices of f(x) and g(x) to determine the type of transformation.The vertex of f(x) is (9,−2) and the vertex of g(x) is (9,−8). The x-coordinates of the vertices are the same, which means there is no horizontal shift. The y-coordinate of the vertex of g(x) is 6 units lower than the y-coordinate of the vertex of f(x), indicating a vertical shift.
Determine Shift Direction: Determine the direction of the vertical shift. Since the y-coordinate of the vertex of g(x) is −8 and the y-coordinate of the vertex of f(x) is −2, the graph has moved down by 6 units.
