Answer:

a) 1

b) 2

c) 2

Step-by-step explanation:

a) f(2) means find the output for \frac{1}{2}x when x=2.

\frac{1}{2}(2)

\frac{2}{2}

1

b) f^{-1}(1) means find the output for 2x when x=1

2(1)

2

c) If f and f^{-1} are truly inverses then f(f^{-1}(u))=u and f^{-1}(f(u))=u as long as u satisfies the domains.

So we should be able to conclude that f^{-1}(f(2))=2 with no work.

However, I will also show work.

f^{-1}(f(2))

f^{-1}(1)    since    f(2)=1 from part a.

2            since    f^{-1}(1)=2 from part b.

Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. Scientist B dissolved 2.0 pounds of salt into 7.0 pints of wa
solong [7]

The scientist that made a more concentrated salt solution is scientist A.

<h3>How to compute the value?</h3>

Since Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. The concentration will be:

= 1/3 = 0.33

Scientist B dissolved 2.0 pounds of salt into 7.0 pints of water. The concentration will be:

= 2/7

= 0.285

Therefore, the scientist that made a more concentrated salt solution is scientist A.
