fill-in-the-blank question

e^2/2+ 1/2

-8/9

1 and 4

{3=

(-infinity, -2), (0, 1/2), (2/3, 1)

-5/4=

Y=2X+ 1

2 1 The title symbol is not easy to type, sorry.

(-1/2,0), (0,+infinity)

The second question, I use drawing, which is not very good.

Finally, I hope I can take the exam in good faith, fail this time, sum up the lessons and work hard next time.
