Q. What kind of transformation converts the graph of f(x)=−5(x+7)2−5 into the graph of g(x)=−5x2−5?Choices:(A) translation 7 units down(B) translation 7 units up(C) translation 7 units left(D) translation 7 units right
Identify Vertex Function: Identify the vertex of the function f(x). The function f(x)=−5(x+7)2−5 is in vertex form, where the vertex (h,k) can be found directly from the equation. The vertex of f(x) is at (−7,−5).
Identify Vertex Function: Identify the vertex of the function g(x). The function g(x)=−5x2−5 is also in vertex form, with the vertex at (0,−5).
Determine Transformation Type: Determine the type of transformation. The vertex of f(x) is at (−7,−5) and the vertex of g(x) is at (0,−5). The y-coordinates of the vertices are the same, so there is no vertical shift. The x-coordinate of the vertex of f(x) is −7, and the x-coordinate of the vertex of g(x) is (−7,−5)0. This indicates a horizontal shift.
Determine Horizontal Shift: Determine the direction and magnitude of the horizontal shift. To go from an x-coordinate of −7 to an x-coordinate of 0, you would need to shift the graph to the right by 7 units.
Match Transformation Choices: Match the transformation to the given choices.The graph of f(x) has been shifted 7 units to the right to obtain the graph of g(x). This matches choice (D) translation 7 units right.
