Q. What kind of transformation converts the graph of f(x)=−4(x−7)2+1 into the graph of g(x)=−4x2+1?Choices:(A) translation 7 units left(B) translation 7 units down(C) translation 7 units right(D) translation 7 units up
Find Vertex:f(x)=−4(x−7)2+1Find the vertex of the given function.Compare f(x)=−4(x−7)2+1 with the vertex form y=a(x−h)2+k.Vertex of f(x): (7,1)
Compare Functions:g(x)=−4x2+1Find the vertex of the transformed function.Compare g(x)=−4x2+1 with the vertex form y=ax2+k.Vertex of g(x): (0,1)
Horizontal or Vertical?: We found:Vertex of f(x)=(7,1)Vertex of g(x)=(0,1)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)=(7,1)Vertex of g(x)=(0,1)Did f(x) shift to the left or right to become g(x)?The x-coordinates of the vertices are 7 and 0 respectively.On a number line, 0 lies to the left of 7.f(x) shifts towards the left.
Identify Transformation: We found that f(x) shifts towards the left.Identify the transformation from (7,1) to (0,1).Calculate the distance between the x-coordinates of the vertices.∣7−0∣=∣7∣=7The graph of f(x) shifts 7 units to the left.
