Question Exercise 2.2 - Requesting Clarification

Exercise 2.2 asks to verify the bound of Theorem 2.4 in the three cases of Example 2.2


on (i) it mentions h(x) = sign (x - alpha)

This made me confuse.

The whole question is not clear to me.

Would anyone help? Any tip or reply is appreciated!

Default Re: Exercise 2.2 - Requesting Clarification

IMHO, there is no need to use the formula h(x)=sign(x-a) (it's just a formula for postive rays) to verify theorem 2.4 because the inequality depends not on a hypothesis but on the growth function.

It's enough to show that the LHS and RHS of the theorem inequality holds. You know growth functions for all the cases.
