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?

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.
