Luna makes a wish every time she passes a fountain, and tosses a few coins she has left as a linear function of wishes made. what is the rate of change in this function?

Rate of change of the function = (-3)

Step-by-step explanation:

Luna makes a wish every time when she passes a fountain and tosses few coins.

Table attached to the question shows the coins left with every wish she made.

From the given table

Wish      1    2     3    4    

Coins   25  22  19   16

Now we have to calculate the rate of change of the function.

Rate of change = (Number of coins left after wish 2 - Number of coins left after wish 1)/ (wish 2 - wish 1)

Rate of change = (22 - 25)/(2-1) = (-3)/1 = (-3)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
