These question are from my study guide for my final and i have permission from the teacher to ask for help so b4 deleting my feed might want to ask now that that is out of the way. I got the answer for some of them the rest i need help on any help is appreciated. Will give brainliest if correct

Answerthe distance to nearby stars;

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:    

This statement is true i just took the test

You this is right
