Table II fill-in: 1.661 (instead of the 2 that's there)
Step-by-step explanation:
The functions shown in Table I and II are inverses of each other. This means that the x's for Table I are the y's in Table II. And the y's in Table I are the x's in Table II.
So look at Table II, there is a coordinate pair
(7, 1.404). Switch the x and y and you get (1.404,7) That's your answer to fill in on Table I.
