Q. What kind of transformation converts the graph of f(x)=5(x+7)25f(x) = -5(x + 7)^2 - 5 into the graph of g(x)=5x25g(x) = -5x^2 - 5?\newlineChoices:\newline(A) translation 77 units down\newline(B) translation 77 units up\newline(C) translation 77 units left\newline(D) translation 77 units right
  1. Identify Vertex Function: Identify the vertex of the function f(x)f(x). The function f(x)=5(x+7)25f(x) = -5(x + 7)^2 - 5 is in vertex form, where the vertex (h,k)(h, k) can be found directly from the equation. The vertex of f(x)f(x) is at (7,5)(-7, -5).
  2. Identify Vertex Function: Identify the vertex of the function g(x)g(x). The function g(x)=5x25g(x) = -5x^2 - 5 is also in vertex form, with the vertex at (0,5)(0, -5).
  3. Determine Transformation Type: Determine the type of transformation. The vertex of f(x)f(x) is at (7,5)(-7, -5) and the vertex of g(x)g(x) is at (0,5)(0, -5). The yy-coordinates of the vertices are the same, so there is no vertical shift. The xx-coordinate of the vertex of f(x)f(x) is 7-7, and the xx-coordinate of the vertex of g(x)g(x) is (7,5)(-7, -5)00. This indicates a horizontal shift.
  4. Determine Horizontal Shift: Determine the direction and magnitude of the horizontal shift. To go from an x-coordinate of 7-7 to an x-coordinate of 00, you would need to shift the graph to the right by 77 units.
  5. Match Transformation Choices: Match the transformation to the given choices.\newlineThe graph of f(x)f(x) has been shifted 77 units to the right to obtain the graph of g(x)g(x). This matches choice (D) translation 77 units right.
