If a vertical line passes through the supposed function at only one spot then you have a function.

Does a sideways parabola represent a function?

No, it does not. You can tell if something is a function or not by using the vertical line test. If there is more than one point at any vertical line, it is not a function.

Is a parabola a graph of a function?

Yes, a parabola can represent the graph of a function, specifically a quadratic function of the form ( y = ax^2 + bx + c ). However, not all parabolic shapes qualify as a function; for instance, if a parabola opens sideways (like ( x = ay^2 + by + c )), it fails the vertical line test, which states that a function must have only one output for each input. Thus, while upward or downward-opening parabolas are indeed functions, sideways-opening parabolas are not.

Why is any parabola that opens upward or downward a function?

It is a function because for every point on the horizontal axis, the parabola identified one and only one point in the vertical direction.


Is a parent function a parabola?

A parent function is a basic function that serves as a foundation for a family of functions. The quadratic function, represented by ( f(x) = x^2 ), is indeed a parent function that produces a parabola when graphed. However, there are other parent functions as well, such as linear functions and cubic functions, which produce different shapes. Therefore, while the parabola is one type of parent function, it is not the only one.


What is a parabola that opens to the right called?

It is a square root mapping. This is not a function since it is a one-to-many mapping.
