Which of the following is a question you should ask yourself when solving a problem?

a. how does it make me feel?
b. who can i blame?
c. how can i ignore it?
d. why did this happen to me

I think the correct answer would be D. When solving a problem, it is important that you first know the root cause of a problem. So, you ask yourself why such a problem happens to you. From that, you can trace back everything that happened and determine what is the cause.

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:
