    Is g(x) = 1/(x^2+1) Concave Down on Which Intervals?

    WOW! You have been so much help! I got X= sqrt of (1/3) So the function is concave down for all X values between -< X < + of sqrt (1/3) I have been going crazy trying to figure this is out! Thank you for your time :)

    Is g(x) = 1/(x^2+1) Concave Down on Which Intervals?

    Ok, so for the 1st derivative I have: -2x/(x^2+1)^2 Second: -6x^2-2/ (x^2+1)^2 Do I need to factor the denom? Also, you stated that I need to determine the values on either side of the inflection points, I should do that with my calculator, right? So, if I have this correct...

    Is g(x) = 1/(x^2+1) Concave Down on Which Intervals?

    Homework Statement For what intervals is g(x) = 1/(x^2+1) concave down? Homework Equations Quotient Rule The Attempt at a Solution OK, so I have found the first and second derivative, but I am confused as to how I should use them to find where the function is concave down. Do I...

    Programs What can I expect as a civil engineering major?

    Hello everyone! I am currently finishing up my physics and calc, and although it's been a little tough, I am determined to complete my studies. I don't know of any civil majors in this forum, however, I was hoping someone could share their experiences with me regarding the major. Thanks in...
