Quadratic functions skipped in pre-calculus?

Click For Summary

Discussion Overview

The discussion revolves around the coverage of quadratic functions in a pre-calculus course and their relevance to calculus. Participants express concerns about whether skipping this topic is appropriate and what foundational knowledge is necessary for success in calculus.

Discussion Character

  • Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions the omission of quadratic functions from the syllabus and wonders if self-study is necessary for calculus.
  • Another participant suggests that knowing how to find the roots of quadratic functions is essential, but implies that other aspects can be skipped since they will be addressed in calculus.
  • A participant notes that the course includes a chapter on zeroes of higher degree polynomials, indicating a belief that this may suffice for the course's objectives.
  • There is a humorous acknowledgment that the quadratic equation is a fundamental concept that cannot be easily forgotten, despite the desire to move past it.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of covering quadratic functions in pre-calculus, with some believing it is essential while others feel it can be omitted. The discussion remains unresolved regarding the adequacy of the course content.

Contextual Notes

Some participants rely on assumptions about the sufficiency of higher degree polynomial coverage, and there is uncertainty about the implications of skipping quadratic functions for calculus readiness.

Hello,

I have a quick question regarding Calculus and what should be covered in pre-cal.

I'm currently in a pre-cal course and according to the syllabus it seems the teacher is skipping over quadratic functions. I only noticed because for the most part her course just follows along with the book but the quadratics were one of the few sections not covered.

Should I self study? Is there something special about quadratic functions that I need to know for Calc?

Make sure that you're able to find the roots of the quadratic function. The rest can safely be skipped as it will be covered in calculus anyway (and it will be covered better in calculus as you don't need to memorize silly formula's anymore).
 
ok!

there is a chapter covering zeroes of polynomials "of higher degree" which seems to be everything over 3rd order, I'm guessing she felt that would be enough. I suppose I should have trusted, eh?

I'm looking forward to forgetting that quadratic equation =)

Sadly, the quadratic equation is about the only one you can not forget :biggrin:
 
oops! good to know...
