Really basic quadratic function problem

Click For Summary

Discussion Overview

The discussion revolves around a problem related to quadratic functions, specifically focusing on the characteristics of these functions and the participant's struggle to formulate a solution. The scope includes conceptual understanding of functions and their properties.

Discussion Character

  • Exploratory, Conceptual clarification, Homework-related

Main Points Raised

  • One participant expresses difficulty in finding a solution to a quadratic function problem, indicating they are new to the topic.
  • Another participant asserts that the function cannot be a function of x because it yields two different values of y for some values of x, suggesting an alternative expression where x is a function of y.
  • A later post reiterates the previous point about the function's nature and mentions a problem related to shifting the parabola upwards.
  • One participant later claims to have solved the problem without providing details on the solution.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the nature of the function, as there are differing views on whether it can be classified as a function of x. The discussion remains unresolved regarding the specifics of the solution.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the function's properties and the lack of detailed mathematical steps leading to the claimed solution.

I can't come up with this function for hours:

I just started to learn quadratic functions so there must be an obvious solution for this which I clearly missed...

It has two different values of y for some values of x. It cannot be a function of x. You can find an expression for f such that x=f(y).

I am awared of that, the closest thing that I can come up with looks like this:

I have a problem of shifting the entire parabola upwards
