please anyone?

this is calc 1

>> No.4885196

Yes, most people here can easily do your trival Calc 1.

No, nobody will check your homework - check with a friend or somebody else who's taking the same class. For Christ's sake, this isn't a homework board.

i'm not sure if those are the right zeros tho..

or roots? can critical numbers be values that are not roots?

wolfram alpha is saying that its only roots are 0 and 1? that is making me doubt my crit numbers..

6) 10, (x-1)^4 and 1/(x+1)² are always positive
1/(x-2)^3 <0 <=> x<2
x<0 <=> x<0
So x/(x-2)^3 <0 <=> 0<x<2
So f(x) <0 <=> 0<x<2

<3 bro. Good luck. But you do seriously need to learn this stuff. You can't always rely on wolfram. best of luck in the future. And /sci/ isn't the best place to post your shit either. Usually I creep on those reddit sites I posted below and respond to just about everyone i'm able to understand. Just give me a hidden message or something at the end your post "Potato Waffles" or some shit. I don't know.

Again, Good luck.

Also, Porn again. Fuck you guys.

For the first trig questions, I got:

Interval of increase: x E { (0, 2pi/3), (4pi/3, 8pi/3) }

local min. at (4pi/3 , 4pi/3 - sqrt(3))

concave down when x E { (0, pi), (2pi, 3pi) }
