Then discuss its purpose and how the interaction among the speaker, audience, and subject affects the text. How does the letter appeal to ethos, pathos, and logos? Finally, how effective do you believe Keller's letter is, and why?

I am not sure Im rlly sorry though

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:
