Q. What kind of transformation converts the graph of f(x)=−6∣x−4∣+1 into the graph of g(x)=−6∣x−4∣+8?Choices:(A) translation 7 units left(B) translation 7 units down(C) translation 7 units up(D) translation 7 units right
Identify Vertex f(x): Identify the vertex of the function f(x)=−6∣x−4∣+1. The vertex of the absolute value function f(x)=−6∣x−4∣+1 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 constant term, which is +1. Therefore, the vertex of f(x) is (4,1).
Identify Vertex g(x): Identify the vertex of the function g(x)=−6∣x−4∣+8. Similarly, the vertex of the absolute value function g(x)=−6∣x−4∣+8 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 constant term, which is +8. Therefore, the vertex of g(x) is (4,8).
Determine Transformation: Determine the transformation from f(x) to g(x). The transformation from f(x) to g(x) involves a change in the y-coordinate of the vertex from 1 to 8. This is a vertical shift. To find the amount of the shift, subtract the y-coordinate of the vertex of f(x) from the y-coordinate of the vertex of g(x): g(x)1. This indicates a translation g(x)2 units up.
