Q. What kind of transformation converts the graph of f(x)=3(x−7)2+8 into the graph of g(x)=3(x−7)2−2?Choices:(A) translation 10 units right(B) translation 10 units up(C) translation 10 units left(D) translation 10 units down
Find Vertex:f(x)=3(x−7)2+8Find the vertex of the given function.Compare f(x)=3(x−7)2+8 with the vertex form y=a(x−h)2+k.Vertex of f(x): (7,8)
Compare Functions:g(x)=3(x−7)2−2Find the vertex of the transformed function.Compare g(x)=3(x−7)2−2 with the vertex form y=a(x−h)2+k.Vertex of g(x): (7,−2)
Vertical Transformation: We found:Vertex of f(x)=(7,8)Vertex of g(x)=(7,−2)Is the transformation horizontal or vertical?Since the x-values of the vertices are the same and the y-values have changed, the transformation is vertical.
Shift Direction: We have:Vertex of f(x)=(7,8)Vertex of g(x)=(7,−2)Did f(x) shift up or down to become g(x)?The y-coordinate of the vertex decreased from 8 to −2.f(x) shifts downwards.
Identify Transformation: We found that f(x) shifts downwards.Identify the transformation from (7,8) to (7,−2).Calculate the vertical distance between the two vertices.∣8−(−2)∣=∣8+2∣=∣10∣=10The graph of f(x) shifts 10 units down.
