Q. What kind of transformation converts the graph of f(x)=7(x+3)2+9 into the graph of g(x)=7(x−4)2+9?(A) translation 7 units right(B) translation 7 units left(C) translation 7 units up(D) translation 7 units down
Find Vertex:f(x)=7(x+3)2+9Find the vertex of the given function.Compare f(x)=7(x+3)2+9 with the vertex form.Vertex of f(x): (−3,9)
Compare Functions:g(x)=7(x−4)2+9Find the vertex of the transformed function.Compare g(x)=7(x−4)2+9 with the vertex form.Vertex of g(x): (4,9)
Horizontal or Vertical?: We found:Vertex of f(x)=(−3,9)Vertex of g(x)=(4,9)Is the transformation horizontal or vertical?Since the y-values of the vertices are the same and the x-values change, the transformation is horizontal.
Left or Right Shift?: We have:Vertex of f(x)=(−3,9)Vertex of g(x)=(4,9)Did f(x) shift to the left or right to become g(x)?The x-coordinates of the vertices are −3 and 4 respectively.On a number line, 4 lies to the right of −3.f(x) shifts towards the right.
Identify Transformation: We found that f(x) shifts towards the right.Identify the transformation from (−3,9) to (4,9).∣−3−4∣=∣−7∣=7The graph of f(x) shifts 7 units to the right.
