Idon't understand this question. does anyone know how to do it?

y = 8(.88)^x

y = 4.221855 for the fifth reduction

Step-by-step explanation:

We can use the formula

y =ab^x

where a =the initial value

b= 1 -percent decrease

a = 8 inches

b = 1-12%

   = 1-.12

   = .88

y = 8 (.88)^x

The fifth reduction is

y = 8 (.88) ^5

y = 4.221855

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

it has the same slope and a different y-intercept

hope this : )
