A question about the introduction

I am looking at the first paragraph of the introduction and see that “We have seen that the time complexity of an algorithm can be expressed as a polynomial.” I am not quite sure where I saw that; this is the first chapter of the first module of “acing C++ coding interviews.” Am I missing some prerequisite? Could someone lead me to the right place? Thanks!
