This is essentially unreadable. Please repost the image right side up and fix the fuzziness.

Can you type your work here?

Where you've obtained a numerical value in your working, how have you verified it?

Never mind, I turned it in already, no thanks to you. Can't you and others like you, do one simple task: to check my homework, to see if I did them correctly? So, don't give me more questions, just do as I requested, after all this website is suppose to help me get some response, not more questions after my initial question. P.S if you don't understand my homework, then skip me or inform others who understand this type of math work. Please stop wasting my time.

LOL!
You know we are unpaid volunteers, right?
You want to boss people around, then pay them and they'll do all you want. If not, lose the attitude.

WHAT IS THIS WEBSITE FOR? Is it maybe, oh I don't know to ask and receive help, not ask and receive unhelpful responses such as: more useless questions, that the person didn't even get his/her initial question responded. So, far your an unhelpful volunteer, if you can't help then why waste my time, when I came on here to seek actual help on a math forum for obviously math related help, idiot.

The first function mentioned was symmetrical about the line x = 0, yet your answers didn't seem to reflect that. Your image was hard to read and didn't show all of your written working. Also, you hadn't shown how some of your answers were obtained. These combined to make it difficult to know what exactly caused incorrect answers. Google can draw a graph for you, allowing you (in most cases) to see whether your numerical answers seem to be correct.
