Questions Review / Help

[Umbra]

This is my first post and I'm just looking for someone to look over my answers and help out with three questions or so.
I've included the .docx file with all of my answers and the questions (in the .zip for uploading purposes) for anyone that can help me out.

Thanks a million!

#11 in order for 2 lines to be parallel they need to have the same slope (m=8) so you need to set f'(x)=8, solve for x and y and now you should be able to find the line using this formula y-y1=m(x-x1)
hope that helps
