Answer:
-4
Step-by-step explanation:
The average rate of change of a function f(x) between two points x = a and x=b is given by,
This can be understood with a simpler example, the straight line.
In this case, the rate of change of the 'function' is given by the slope,
;
being two points on the straight line.
So, for the given problem,
a = -2
b = 2
Hence, average rate of change of 
The new ratio of the number of cookies in Jar A to the number of cookies in Jar B in the end is 5 : 19
<h3>How to find ratio</h3>
Ratio of jar A to jar B = 3 : 8
Jar B = 1/2 of A + B
= 1/2 × 3 + 8
= 3/2 + 8
= (3+16) /2
= 19/2
Jar A = 3 - 1/2
= (6-1) /2
= 5/2
New ratio of jar A to jar B = 5/2 : 19/2
= 5/2 ÷ 19/2
= 5/2 × 2/19
= 5/19
= 5 : 19
