Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous year. Write an exponential function that models the value in dollars of the boat x years after Marcus's purchase.

Question 18 options:

f(x)=0.919(56900)x

f(x)=56900(0.919)x

f(x)=0.081(56900)x

f(x)=56900(0.081)x

i think the answer is b.

step-by-step explanation:

not 100% sure though.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

the answer will be b x² +x-1
