 P: 3 1. The problem statement, all variables and given/known data For every x over ℝ, find min, max of following expression 2. Relevant equations y=8x4/(x2+1)2+4x/(x2+1)+1 3. The attempt at a solution I've graphed it but it's really complex. How can I find that points? Thank you so much :)

"every x over ℝ" - this shows up as a box in my browser.

I'm assuming that you wrote the right side correctly, where there are three terms, with 1 being a term by itself. Rewrite the right side as a single rational expression. What is the least common denominator?
