Due to crime rates in a certain city, home values began to decrease by 4% each year. If a home was purchased in 2015 for $315,000, write and use an exponential function to determine the amount the house will be worth in 2020. Round to the nearest whole dollar.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

0.4 liters = 400 milliliters (multiply the volume value by 1000 and it give you the answer). hope this ! ^-^
