Agood letter of recommendation should not provide colleges with a. a history of the student's accomplishments. b. a picture of the student's abilities. c. a history of the student's coursework and grades. d. a picture of the student's desire to be successful.

Wouldn't the answer be B, a picture of the students  abilities

Ibelieve it is d but i may be wrong

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:
