Find Vertex of f(x): Analyze the given function f(x)=−9(x−9)2−9 to find its vertex.The vertex form of a quadratic function is f(x)=a(x−h)2+k, where (h,k) is the vertex of the parabola.For f(x), the vertex is at (h,k)=(9,−9).
Find Vertex of g(x): Analyze the transformed function g(x)=−9(x+1)2−9 to find its vertex.Using the vertex form, the vertex of g(x) is at (h,k)=(−1,−9).
Compare Vertices for Transformation: Determine the type of transformation by comparing the vertices of f(x) and g(x). The vertex of f(x) is (9,−9), and the vertex of g(x) is (−1,−9). Since the y-coordinates of the vertices are the same, there is no vertical shift. The x-coordinate of the vertex of g(x) is 10 units to the left of the x-coordinate of the vertex of f(x).
Calculate Horizontal Shift: Calculate the exact horizontal shift from the vertex of f(x) to the vertex of g(x). The shift is the difference in the x-coordinates of the vertices: 9−(−1)=9+1=10. The graph of f(x) is shifted 10 units to the left to obtain the graph of g(x).
