Q. What kind of transformation converts the graph of f(x)=5(x−1)2+1 into the graph of g(x)=5(x−1)2−2?Choices:(A) translation 3 units down(B) translation 3 units right(C) translation 3 units left(D) translation 3 units up
Find Vertex Function:f(x)=5(x−1)2+1Find the vertex of the given function.Compare f(x)=5(x−1)2+1 with the vertex form y=a(x−h)2+k.Vertex of f(x): (1,1)
Compare with Vertex Form:g(x)=5(x−1)2−2Find the vertex of the transformed function.Compare g(x)=5(x−1)2−2 with the vertex form y=a(x−h)2+k.Vertex of g(x): (1,−2)
Find Transformed Function Vertex: We found:Vertex of f(x)=(1,1)Vertex of g(x)=(1,−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.
Identify Vertical Transformation: We have:Vertex of f(x)=(1,1)Vertex of g(x)=(1,−2)Did f(x) shift up or down to become g(x)?The y-coordinates of the vertices are 1 and −2 respectively.On a number line, −2 lies below 1.f(x) shifts downwards.
Identify Direction of Shift: We found that f(x) shifts downwards.Identify the transformation from (1,1) to (1,−2).∣1−(−2)∣=∣3∣=3The graph of f(x) shifts 3 units down.
