Option B: is the new equation
Explanation:
The given equation is
We need to find the new graph which is shifted 7 units up and 4 units right.
First, we shall shift the graph 7 units up.
The general formula to shift the graph b units up is given by
Thus, to shift the graph 7 units up, let us substitute and
in the general formula, we have,
Now, we shall shift the graph 4 units right.
The general formula to shift the graph b units right is given by
Thus, to shift the graph 4 units right, let us substitute and
in the above equation, we have,
Therefore, the new equation is
Therefore, Option B is the correct answer.
