the problem Use. Find that the wide the axe on dh second directive a tive by square over the X square which, while some thirty Is that sure Concave upward. You're actually physical to Santy. Why is he goto sign two champs, Tio, He's between the right time. First the computer T y the axe. This is the coat with you. Why he he over? Yeah, thanks. Yeah. Why did he is assigned hootchy times two on the X ditty is negative. Fine. Now we computed the second derivative. This's too Yeah, you wide yaks over Jax to keep Oh, so the DDT divide yaks? We use caution rule since he called to negative sign Squire on it is year. This is two times make you sign to teach ums too. I'm still negative. Fine. On the minus two hams. Sign to tea. I'm selective. Sign she over the ex titties. Negative sign He and this's iko too. Rosa numerator. This's or sign he sign. Who is he? Plus, who'd hamzik assigned? Key Sign to a T over negative sign. Hey, two, three pounds Now for which values off T is a curve. Concave upward. We now want the second narrative is security and zero Then a curve on cave upward of a light He y square, x squared riches and cereal And then now this in clarity we know one cheese between zero and pi. Scientist E is always riches and zero, isn't it? So the denominator is always s'mores and zero things. That a lot. This one is great, isn't zero So it is equivalent to see numerator is also smaller than zero. So we have all time. Sign he I'm through with you. Us two ham signed signed here. Sign two fifty is smaller than zero. Now we use shoe tree God in peace assigned to Teo Is he going to two times? Signed signs on DH Sign to Teo Record sign. He's squire minus sign Key square. This is total to Tom's call sign. He's square minus one by this two identities. We have four time signed here. I'm too damn sign Sign Last two times. Assigned here times two times. Call sign. He swam once one smaller than zero. We help ate ham. Signed his squire with hand use one minus co sign. It's quiet in times Signed you last two times. Call Sign He times two times consigned. His squire, minus one is smaller. Zero Was this one the kind, right? This's two times call sign he Terms or Tom's one Minus was fine. Esquire class two times consigned. He's quiet, minus one smaller than zero. This is two times call sign here three minus two Assigned. It's Quinn, Smaller zero. Since we know Sandy Square and smaller than one So two times cause anti Square is smaller than to this part is greater than zero. So we have we'LL sign he squire Sam Qi smaller than zero. And since tea is between zero two ply So we have was from this one we have He is the last to know Hi. Over too. Too high now one t It's between pie over to pie The curve. I'm careful upward
