Did you copy and paste that into Word from a pdf file? Unfortunately, that makes it pretty much unreadable on my PC.

These are easy problems. Confused about Q1, integrate between 1 and y?

I'm confused about Q1. Where are x and y supposed to be the specified function arguments and where are they supposed to be the variables of integration?

Senior Member Joined: Mar 2015 From: Universe 2.71828i3.14159 Posts: 169 Thanks: 65 Math Focus: Area of Circle  Q2. $(x+y+z) = \dfrac{x+y}{2} + \dfrac{y+z}{2} + \dfrac{z+x}{2} \ge \sqrt{xy} + \sqrt{yz} + \sqrt{zx} \ge \sqrt{xy+yz+zx}$ Q3. y and z in terms of x, and for $x \in Z^+$ find the minimum value of f(x). Q4 is too easy. And there is still something wrong with Q1. Last edited by skipjack; November 1st, 2019 at 03:27 AM.
