A$$ car$-$leasing firm must decide how much to charge for maintenance on the cars it leases. After careful$$ study, the firm determines that the rate of$$ maintenance, M$($x$),$ on a new car will be approximately$$ M$($x$)=56(1+$x$^2)$ dollars per$$ year, where x is the number of years the car has been in use. What total maintenance cost can the company expect for a$2-$year lease? What minimum amount should be added to the monthly lease payments to pay for maintenance on a$2-$year lease? Write a definite integral to find the total maintenance cost for a$2-$year lease. The total maintenance cost the company can expect on a$2-$year lease is $$$$?$
