Q. What kind of transformation converts the graph of f(x)=7(x−8)2+5 into the graph of g(x)=7(x+1)2+5?Choices:(A) translation 9 units up(B) translation 9 units right(C) translation 9 units left(D) translation 9 units down
Find Vertex Function:f(x)=7(x−8)2+5Find the vertex of the given function.Compare f(x)=7(x−8)2+5 with the vertex form.Vertex of f(x): (8,5)
Compare with Vertex Form:g(x)=7(x+1)2+5Find the vertex of the transformed function.Compare g(x)=7(x+1)2+5 with the vertex form.Vertex of g(x): (−1,5)
Find Transformed Vertex: We found:Vertex of f(x)=(8,5)Vertex of g(x)=(−1,5)Is the transformation horizontal or vertical?Since the y-values of the vertices are the same and only the x-values change, the transformation is horizontal.
Compare with Vertex Form: We have:Vertex of f(x)=(8,5)Vertex of g(x)=(−1,5)Did f(x) shift to the left or right to become g(x)?The x-coordinates of the vertices are 8 and −1 respectively.On a number line, −1 lies to the left of 8.f(x) shifts towards the left.
Identify Transformation: We found that f(x) shifts towards the left.Identify the transformation from (8,5) to (−1,5).Calculate the distance between the x-coordinates of the vertices.∣8−(−1)∣=∣9∣=9The graph of f(x) shifts 9 units to the left.
