5 numbers are significant.
Answer:
3.65 ≤ x < 3.75.
Step-by-step explanation:
Lowest value = 3.65 and highest is < 3.75.
3.65 ≤ x < 3.75.

Answer:
The inverse of the function is .
Step-by-step explanation:
The function provided is:
Let .
Then the value of <em>x</em> is:
For the inverse of the function, .
⇒

In the first octant, we assume
, so we can ignore the caveats above. Now,
so that the only critical point in the region of interest is (1, 2, 2), for which we get a maximum value of
.
We also need to check the boundary of the region, i.e. the intersection of
with the three coordinate axes. But in each case, we would end up setting at least one of the variables to 0, which would force
, so the point we found is the only extremum.
