Q. What kind of transformation converts the graph of f(x)=2∣x−5∣+1 into the graph of g(x)=2∣x+5∣+1?Choices:(A) translation 10 units down(B) translation 10 units up(C) translation 10 units left(D) translation 10 units right
Identify Vertex of f(x): Identify the vertex of the function f(x)=2∣x−5∣+1. The vertex of the absolute value function f(x)=2∣x−5∣+1 is at the point where the expression inside the absolute value is zero. This occurs at x=5. The y-coordinate of the vertex is the value of the function when x=5, which is f(5)=2∣5−5∣+1=2∣0∣+1=2(0)+1=1. Therefore, the vertex of f(x) is (5,1).
Identify Vertex of g(x): Identify the vertex of the function g(x)=2∣x+5∣+1. Similarly, the vertex of the absolute value function g(x)=2∣x+5∣+1 is at the point where the expression inside the absolute value is zero. This occurs at x=−5. The y-coordinate of the vertex is the value of the function when x=−5, which is g(−5)=2∣−5+5∣+1=2∣0∣+1=2(0)+1=1. Therefore, the vertex of g(x) is (−5,1).
Determine Transformation Type: Determine the type of transformation from f(x) to g(x). The vertex of f(x) is (5,1) and the vertex of g(x) is (−5,1). The transformation from f(x) to g(x) involves a horizontal shift, since the y-coordinates of the vertices are the same, but the x-coordinates are different. The shift is from g(x)0 to g(x)1, which is a shift of g(x)2 units to the left.
