The graph G that is obtained by sequence of transformation in graph of y.
The graph G is y=3(x−4)2 .
Given:
The graph of y=x2 is shifted by 4 units right, then a vertical stretch by a factor 3 .
Concept Used:
The graph of y=f(x) is translated or shifted horizontally left or right according as:
1) If y=f(x−c) , then graph shifted by c units right from y=f(x) .
2) If y=f(x+c) , then graph shifted by c units left from y=f(x) .
And, the graph of y=f(x) is translated or shifted vertically up or down according as:
1) If y=f(x)+c , then graph shifted by c units up from y=f(x) .
2) If y=f(x)−c , then graph shifted by c units down from y=f(x) .
The transformation of horizontal stretches or shrinks from y=f(x) is as follows:
The graph of y=f(xc) transform to horizontal stretches by factor c , when c>1 and horizontal shrinks by factor c when c<1 .
The transformation of vertical stretches or shrinks from y=f(x) is as follows:
The graph of y=c⋅f(x) transform to vertical stretches by factor c , when c>1 and shrinks by factor c when c<1 .
Calculation:
Consider the sequence of transformation,
The graph of function y=x2 is shifted by 4 units right,
So x is replace by (x−4) , that is, y=(x−4)2 .
Thus, the equation y=x2 transform to y=(x−4)2 .
And, in the next transformation, the graph of y=(x−4)2 is stretches vertically by factor 3 ,
So 3 is multiplied to the function, that is y=3(x−4)2 as 3>1 .
Hence, the function y=(x−4)2 transform to y=3(x−4)2 .
Conclusion The equation y=x2 transform to y=3(x−4)2 when graph of y=x2 is shifted by 4 units right, then a vertical stretch by a factor 3 .
