The function f(x)=1200(1.055)x models the balance of an investment x years after it is made. how does the average rate of change between years 21 and 25 compare to the average rate of change between years 1 and 5?

option-B

Step-by-step explanation:

We are given function as

Average rate of change between 21 and 25 years:

we can use formula

so, we have

a=21 and b=25

now, we can plug values

Average rate of change between 1 and 5 years:

we can use formula

so, we have

a=1 and b=5

now, we can plug values

now, we can find ratio

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
