D. 36x^12y^6 is the correct answer
Answer:
f(x)=4−(x−7)
3
Let y=f(x)
So, x=f
−1
(y) ---- ( 1 )
y=f(x)
⇒ y=4−(x−7)
3
⇒ (x−7)
3
=4−y
⇒ x−7=
3
4−y
⇒ x=7+
3
4−y
⇒ f
−1
(y)=7+
3
4−y
.................. [ From ( 1 ) ]
∴ f
−1
(x)=7+
3
4−x

Remember that f(x) = x is a straight line heading from the lower left corner to the upper right corner. But, the graph is moved up two units, so add 2. Thus, the answer is c.
