Q. What kind of transformation converts the graph of f(x)=−7∣x+4∣+7 into the graph of g(x)=−7∣x−3∣+7?Choices:(A) translation 7 units down(B) translation 7 units right(C) translation 7 units left(D) translation 7 units up
Identify Vertex of f(x): Identify the vertex of the function f(x)=−7∣x+4∣+7. The vertex of the absolute value function f(x)=−7∣x+4∣+7 occurs where the expression inside the absolute value is zero, i.e., x+4=0, which gives x=−4. The y-coordinate of the vertex is the constant term outside the absolute value, which is +7. Therefore, the vertex of f(x) is (−4,7).
Identify Vertex of g(x): Identify the vertex of the function g(x)=−7∣x−3∣+7. Similarly, the vertex of the absolute value function g(x)=−7∣x−3∣+7 occurs where the expression inside the absolute value is zero, i.e., x−3=0, which gives x=3. The y-coordinate of the vertex is the same as in f(x), which is +7. Therefore, the vertex of g(x) is (3,7).
Determine Transformation: Determine the transformation from f(x) to g(x). The transformation from f(x) to g(x) involves a horizontal shift from the vertex (−4,7) to the vertex (3,7). The shift is to the right by 7 units since −4+7=3.
