## What is the function for a circle?

The equation of a circle appears as (x – h)2 + (y – v)2 = r2. This is called the center-radius form (or standard form) because it gives you both pieces of information at the same time. The h and v represent the coordinates of the center of the circle being at the point (h, v), and r represents the radius.

## Is a circle on a graph considered a function?

A circle is a set of points in the plane. A function is a mapping from one set to another, so they’re completely different kinds of things, and a circle cannot be a function.

## Is a circle a many to one function?

A relation can also be one to manyor many to many- where x values can have more than one y value. A circle is an example of this of a many to many function. A vertical line can cut through this graph more than once.

## Is a semi circle a function?

Semicircles are functions. Consider a circle with the equation x2 + y2 = r2.

## Is a semi circle an odd or even function?

Rule1:-Odd functions are always symmetrical with respect to the origin. and even function is symmetrical with respect to y axis. hence,standard equation of circle is always even, it never be odd.

## Is a semi circle symmetrical?

In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn). It has only one line of symmetry (reflection symmetry).

## Whats half a circle?

In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn). It has only one line of symmetry (reflection symmetry).

## Does a half circle have a name?

A semicircle is half of a circle.

## Is a half circle a function?

Function defined by a relation in the form f(x) = √r2–x2 or f(x) = − √r2–x2 where r is the radius of a circle centered on the origin point.
