Well, for number 15, this is what I came up with, I hope it is what your teacher is looking for: 
So it starts out with 3 butterflies, and it doubles every minute: 
3x2 = 6  That is for the first minute 
6x2 = 12 That is for the second minute 
12x2 = 24 That is for the third minute 
24x2 = 48 That is for the fourth minute

So, It asks for using the power of 2 in your answer, that is what I came up with for part A. 

For part B I would say something like this: 

X represents the number of butterflies left. 
The equation, using the information above would be this:

48-7 = X
Then simplify, which would leave you with 41 butterflies. 

I hope this helps! :)

1. The perimeter of the square is f(x) = 4x, where x is the side of the square. Find the domain of the function.
Mkey [24]

If the perimeter of the square is 4x then the domain of the function will be set of rational numbers and the domain of the function y=3x+8(3-x) is set of real numbers.

Given The perimeter of the square is f(x)=4x and the function is y=3x+8(3-x)

We will first solve the first part in which we have been given that the perimeter of the square is 4x and we have to find the domain of the function.

First option is set of rational numbers which is right for the function.

Second option is set of whole numbers which is not right as whole number involves 0 also and the side of the square is not equal to 0.

Third option is set of integers which is not right as integers involve negative number also and side of square cannot be negative.

Hence the domain is set of rational numbers.

Now we will solve the second part of the question

f(x)=3x+8(3-x)

we have not told about the range of the function so we can put any value  in the function and most appropriate option will be set of real numbers as real number involve positive , negative and decimal values also.
