Answer:

  • f(x) = 8/√x
  • g(x) = 2x+4

Step-by-step explanation:

For this sort of problem, there can be an infinite number of answers.

It can be convenient to choose one of the simpler answers by looking at the operations that are performed on the variable. Here, you have ...

  • 2 multiplies it
  • 4 is added to the product
  • the square root is taken
  • 8 is divided by that root

You can work from the bottom up and define the outer function (f(x)) to be any of these operations. In our answer above, we have elected to include the "square root" and the "8 divided by that root" in our definition of f.

Then our function g takes care of the other operations.

Leona [35]

Answer: She will pay $64.90 in total.

Step-by-step explanation: The bill at the restaurant comes to $55 and Crystal wants to include an 18% tip.

Now, you will multiply 55 by 0.18, giving you 9.9.

Add that to 55 and you will have your answer.

Have a great day!
