Q. What kind of transformation converts the graph of f(x)=−6(x+9)2−5 into the graph of g(x)=−6(x+4)2−5?Choices:(A) translation 5 units right(B) translation 5 units down(C) translation 5 units left(D) translation 5 units up
Identify Vertex f(x): Identify the vertex of the function f(x). The function f(x)=−6(x+9)2−5 is in vertex form, where the vertex is at (−h,k). For f(x), the vertex is at (−9,−5).
Identify Vertex g(x): Identify the vertex of the function g(x). The function g(x)=−6(x+4)2−5 is also in vertex form. For g(x), the vertex is at (−4,−5).
Type of Transformation: Determine the type of transformation.The y-coordinates of the vertices of f(x) and g(x) are the same, which means there is no vertical shift. The x-coordinates have changed, indicating a horizontal shift.
Direction of Shift: Determine the direction of the horizontal shift. The x-coordinate of the vertex of f(x) is −9, and the x-coordinate of the vertex of g(x) is −4. Since −4 is to the right of −9 on the number line, the graph has shifted to the right.
Magnitude of Shift: Calculate the magnitude of the horizontal shift. The difference in the x-coordinates of the vertices is ∣−9−(−4)∣=∣−9+4∣=∣5∣=5. Therefore, the graph of f(x) has shifted 5 units to the right to become the graph of g(x).
