# A computer valued at $1500 loses 20% of its value each year. a. Write a function rule that models the value of the computer. b. Find the value of the Exponential models ANSWERED asked 2021-05-09 A computer valued at$1500 loses 20% of its value each year. a. Write a function rule that models the value of the computer. b. Find the value of the computer after 3 yr. c. In how many years will the value of the computer be less than \$500? Remember the general form of an exponential function: $$f(x)=a*b^x$$. Given your table and situation, determine values for a and b. Write the appropriate exponential function.

The exponential function is: $$\displaystyle{f{{\left({x}\right)}}}={1500}\cdot{\left({0.8}\right)}^{{x}}$$
