One advantage of check writing is:
you have a written record of your payment

you can use it in atm machines everywhere

you can get cash from atm machines with it

you have to pay a fee for using it in an atm machine

first You have a written record of your payment
checks can't be used in ATM it's piece of paper not a magnetic card

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
