1. Hi everyone,
i've attached you two inequalities that should make sense if you subbing in zero for k (inequality number 1) and for a(inequality number 2) but the text book didn't mention zero as an answer for the range of the values that makes sense in each inequality . just wanted to get your opinion if zero can be an answer for each of blow inequalities thanks. inequality number 1 is +1 at the end not 9, my handwriting is really bad sorry

You'll need to show us the question (in full, via photo) and the answer (in full). (does it perchance say that k is a positive constant?)

See, it says "k is a positive integer" - 0 is not a positive integer. A positive integer is {1, 2, 3, ... }.

I think the book is wrong and you are correct, a = 0 is a valid part of the inequality.

No worries. A-Level textbooks, for the most part, seem to have loads of errors in them.

Exactly, it's been like four or five times that i've found errors in the text book so far
