Question

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?

Answer 1

-3........................

Answer 2

Rate of change of the function = (-3)

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)
