Q. What kind of transformation converts the graph of f(x)=−2∣x−4∣−2 into the graph of g(x)=−2∣x−4∣−6?Choices:(A) translation 4 units right(B) translation 4 units up(C) translation 4 units left(D) translation 4 units down
Identify Vertex of f(x): Identify the vertex of the function f(x)=−2∣x−4∣−2. The vertex of the absolute value function f(x)=−2∣x−4∣−2 is at the point where the expression inside the absolute value is zero, which is at x=4. The y-coordinate of the vertex is the value of the function when x=4, which is f(4)=−2∣4−4∣−2=−2. So, the vertex of f(x) is (4,−2).
Identify Vertex of g(x): Identify the vertex of the function g(x)=−2∣x−4∣−6. Similarly, the vertex of the absolute value function g(x)=−2∣x−4∣−6 is at the point where the expression inside the absolute value is zero, which is at x=4. The y-coordinate of the vertex is the value of the function when x=4, which is g(4)=−2∣4−4∣−6=−6. So, the vertex of g(x) is (4,−6).
Determine Transformation: Determine the transformation from f(x) to g(x). The x-coordinates of the vertices of f(x) and g(x) are the same, so there is no horizontal shift. The y-coordinate of the vertex of g(x) is 4 units lower than the y-coordinate of the vertex of f(x) (g(x)0 compared to g(x)1). This indicates a vertical shift. The transformation is a translation 4 units down.
