Section 2.3
Question 10

Note: y_1 = y_2. The blue and red lines lie directly on top of each other.

You say?

how did you get y_2?

(x^2)-1/(x^2+1) is not = x^4 + x^2 - 1

x^4 + x^2 - 1 = x^2*(x^2 + 1) -1

the graph above is correct

x^4 + x^2 - 1 = x^2*(x^2 + 1) -1

the graph above is correct

yeahhhhh, sorry

 

[nycmathguy]

yeahhhhh, sorry

It's cool.

Note: Keep in mind that I moved into my new place this past weekend. I am daily organizing my stuff. The only time I have for math is on my lunch break at the job on the overnight hours. In a few days, my life should be back to normal.
