Q. What kind of transformation converts the graph of f(x)=6(x+1)2+10 into the graph of g(x)=6(x+9)2+10?Choices:(A) translation 8 units down(B) translation 8 units right(C) translation 8 units left(D) translation 8 units up
Identify Vertex: Identify the vertex of the function f(x). Compare f(x)=6(x+1)2+10 with the vertex form of a parabola. Vertex of f(x): (−1,10)
Compare Functions: Identify the vertex of the function g(x). Compare g(x)=6(x+9)2+10 with the vertex form of a parabola. Vertex of g(x): (−9,10)
Type of Transformation: Determine the type of transformation.Since the y-values of the vertices are the same and only the x-values have changed, the transformation is horizontal.
Direction of Transformation: Determine the direction of the transformation.The x-coordinate of the vertex of f(x) is −1 and the x-coordinate of the vertex of g(x) is −9.Since −9 is to the left of −1 on the number line, the graph has shifted to the left.
Calculate Magnitude: Calculate the magnitude of the transformation.The difference in the x-coordinates of the vertices is |-1 - (-9)| = |8| = 8").\(\newlineThe graph of \$f(x)\) shifts \(8\) units to the left to become \(g(x)\).
