The approximate rate of change in height of a certain shrub in a nursery is given by f'(x) = 14/x, where the height is measured in inches and x represents the number of years since the shrub was planted. After 2 years, the shrub was 17 inches tall. Find the function that gives the height of the shrub x years after it was planted. Assuming that the shrub will be sold when it is 7 years old, approximate its height when it is sold.
f(x) = 14 ln|x| + 17; 34.5 inches
f(x) = 14 ln|x| + 17; 44.2 inches
f(x) = -14/x^2 + 41/2; 20.2 inches
f(x) = 14 ln|x| + 7.3; 34.5 inches
