Q. What kind of transformation converts the graph of f(x)=−2(x+4)2+3 into the graph of g(x)=−2(x−4)2+3?Choices:(A) translation 8 units down(B) translation 8 units left(C) translation 8 units up(D) translation 8 units right
Identify Vertex: Identify the vertex of the function f(x). Compare f(x)=−2(x+4)2+3 with the vertex form of a quadratic function. Vertex of f(x): (−4,3)
Compare Functions: Identify the vertex of the function g(x). Compare g(x)=−2(x−4)2+3 with the vertex form of a quadratic function. Vertex of g(x): (4,3)
Determine Transformation Type: Determine the type of transformation.The vertex of f(x) is (−4,3) and the vertex of g(x) is (4,3).Since the y-values of the vertices are the same and the x-values have changed, the transformation is horizontal.
Determine Transformation Direction: Determine the direction of the transformation. The x-coordinate of the vertex of f(x) is −4 and the x-coordinate of the vertex of g(x) is 4. Since the x-coordinate has increased, the graph has shifted to the right.
Calculate Transformation Distance: Calculate the distance of the transformation.The difference in x-coordinates of the vertices is 4−(−4)=8.The graph of f(x) shifts 8 units to the right.
