The graph of the function \(g(x)=(x+7)^{2}+9\) is obtained from the graph of the function \(f(x)=x^{2}\) when each point on the curve of \(f(x)=x^{2}\) is shifted \(7\) units towards the negative direction of \(x-\) axis and then shifted \(9\) units towards the positive direction of \(y-\) axis.
Further explanation:
The functions are given as follows:
\(\fbox{\begin\\\ \begin{aligned}f(x)&=x^{2}\\g(x)&=(x+7)^{2}+9\end{aligned}\\\end{minispace}}\)
The objective is to determine the transformation or the way in which the graph of the function \(g(x)\) is obtained from the graph of the function \(f(x)\).
Concept used:
Shifting of graphs:
Shifting is a rigid translation because it does not change the size and shape of the curve. Shifting is used to move the curve vertically or horizontally without any change in shape and size of the curve.
The function \(y=f(x+a)\) and \(y=f(x-a)\) is a shift of the curve \(y=f(x)\) horizontally towards negative and positive direction of \(x-\)axis respectively.
The function \(y=f(x)+a\) and \(y=f(x)-a\) is a shift of the curve \(y=f(x)\) vertically towards positive and negative direction of \(y-\)axis respectively.
Step1: Draw the graph of the function \(f(x)=x^{2}\).
Figure 1 (attached in the end) represents the graph of the function \(f(x)=x^{2}\). From figure 1 it is observed that the curve of the function \(f(x)=x^{2}\) is a parabola with origin as the vertex and mounted upwards.
Step 2: Obtain the graph of the function \(g'(x)=(x+7)^{2}\) from the graph of the function \(f(x)=x2\).
The function \(g'(x)=(x+7)^{2}\) is of the form \(y=f(x+a)\).
So, as per the concept of shifting of the graphs the graph of the function \(g'(x)=(x+7)^{2}\) is obtained from the graph of the function \(f(x)=x^{2}\) when each point on the curve of \(f(x)=x^{2}\) is shifted \(7\) units towards the negative direction of \(x-\)axis.
Figure 2 (attached in the end) represents the graph of the function \(g'(x)=(x+7)^{2}\).
In figure 2 the dotted line represents the curve of \(f(x)=x^{2}\) and the bold line represents the curve of \(g'(x)=(x+7)^{2}\).
Step3: Obtain the graph of the function \(g(x)=(x+7)^{2}+9\) from the graph of the function \(g'(x)=(x+7)^{2}\).
The function \(g(x)=(x+7)^{2}+9\) is of the form \(y=f(x)+a\).
So, as per the concept of shifting of graph the graph of the function \(g(x)=(x+7)^{2}+9\) is obtained from the graph of the function \(g'(x)=(x+7)^{2}\) when each point on the curve of \(g'(x)=(x+7)^{2}\) is shifted \(9\) units towards upwards or the positive direction of \(y-\)axis.
Figure 3 (attached in the end) represents the graph of the function \(g(x)=(x+7)^{2}+9\).
In figure 3 the dotted line represents the curve of \(g'(x)=(x+7)^{2}\) and the bold line represents the curve of \(g(x)=(x+7)^{2}+9\).
From the above explanation it is concluded that the graph of the function \(g(x)=(x+7)^{2}+9\) is obtained from the graph of the function \(f(x)=x^{2}\) when each point on the curve of \(f(x)=x^{2}\) is shifted \(7\) units towards the negative direction of \(x-\) axis and then shifted \(9\) units towards the positive direction of \(y-\) axis.
