Q. What kind of transformation converts the graph of f(x)=9(x8)2+3f(x) = -9(x - 8)^2 + 3 into the graph of g(x)=9(x8)25g(x) = -9(x - 8)^2 - 5?\newlineChoices:\newline(A) translation 88 units up\newline(B) translation 88 units right\newline(C) translation 88 units left\newline(D) translation 88 units down
  1. Identify Vertex: Identify the vertex of the function f(x)f(x). The function f(x)=9(x8)2+3f(x) = -9(x - 8)^2 + 3 is in vertex form, where the vertex is given by (h,k)(h, k). In this case, the vertex of f(x)f(x) is (8,3)(8, 3).
  2. Identify Vertex: Identify the vertex of the function g(x)g(x). The function g(x)=9(x8)25g(x) = -9(x - 8)^2 - 5 is also in vertex form, and the vertex is (h,k)(h, k). Here, the vertex of g(x)g(x) is (8,5)(8, -5).
  3. Compare Vertices: Compare the vertices of f(x)f(x) and g(x)g(x) to determine the transformation.\newlineThe vertex of f(x)f(x) is (8,3)(8, 3) and the vertex of g(x)g(x) is (8,5)(8, -5). The xx-coordinates of the vertices are the same, which means there is no horizontal shift. The yy-coordinate of the vertex of g(x)g(x) is lower than that of f(x)f(x), indicating a vertical shift.
  4. Determine Shift: Determine the direction and magnitude of the vertical shift.\newlineTo find the vertical shift, we calculate the difference in the yy-coordinates of the vertices of f(x)f(x) and g(x)g(x).\newlineThe difference is 3(5)=3+5=83 - (-5) = 3 + 5 = 8.\newlineSince the yy-coordinate of g(x)g(x) is lower, the graph has shifted downwards.
  5. Identify Transformation: Identify the correct transformation from the given choices.\newlineThe graph of f(x)f(x) has shifted 88 units down to become the graph of g(x)g(x). This corresponds to choice (D) translation 88 units down.
