A computer is purchased for $1372. Its value in dollars after t years can be approximated by V(t) = 1372 / (3t + 1)^2, where 0 ≤ t ≤ 3. (a) Find the value of the computer 2 years after purchase. (b) At time t = 2 years, use a derivative to estimate how much the value will change within the next year. (a) The value of the computer 2 years after purchase is $. (b) At time t = 2 years, the value of the computer will by approximately dollars within the next year. (Type a whole number.)
