Solve the problem.The approximate rate of change in height of a certain shrub in a nursery is given by 
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 18 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 6 years old, approximate its height when it is sold.
