Step-by-step explanation:
1.5 : 2.5
= 1.5/2.5
15/25
3/5
the ratio is 3 : 5
The average rate of change of a function f(x) over an interval (a, b) is given by
![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%20)
Therefore, given a function, f(x), over an interval (2, 9), the average rate of change of the function can be found using the expression
Answer:
The answer is =A2*B2*C2
