Answer:
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)
