Answer:

Option d.$18 to $30

Step-by-step explanation:

we know that

The quartet earn between $25 and $40 per hour.

If they play for 3 hours

then

($25*3)=$75

($40*3)=$120

the quartet will earn between $75 and $120

Divide the money equally between the four members

$75/4=$18.75

$120/4=$30

therefore

Each member can make between $18.75 and $30

Answer: They are inverses of each other

============================================================

Explanation:

We need to check two things:

f(g(x)) = x
g(f(x)) = x

If both of those equations are true, then f and g are inverses of each other.

----------------

Part 1

$f(x) = -3x-12\\\\f(g(x)) = -3( g(x) )-12\\\\f(g(x)) = -3\left( \frac{-12-x}{3} \right)-12\\\\f(g(x)) = 12+x-12\\\\f(g(x)) = x\\\\$

So far, so good. Now we need to check the other equation mentioned.

------------------

Part 2

$g(x) = \frac{-12-x}{3}\\\\g(f(x)) = \frac{-12-( f(x) )}{3}\\\\g(f(x)) = \frac{-12-( -3x-12 )}{3}\\\\g(f(x)) = \frac{-12+3x+12}{3}\\\\g(f(x)) = \frac{3x}{3}\\\\g(f(x)) = x\\\\$

That works out as well. Both equations mentioned are true, which confirms the two original functions are inverses of one another.
