I believe your answer is C
Hi,

Domain of (fog)(x) is R \ {13} =(-oo 13[ U ]13 +oo)
The x-value increases by a factor of 5 from 1.6 to 8 between the two points. Because the variation is inverse, the y-value must decrease by a factor of 5 between the two points.
6/5 = 1.2
The second point is (8, 1.2), corresponding to the 4th selection.
Simple....
we know the formula you need to use is y=mx+b....
plug 'n chug....
3=3(1)+b
3=3+b
-3 -3
b=0
Thus.....y=3x
Thus, your answer.
First make it into a decimal then move the decimal place to place to the left.
