## Does a curve have to be continuous?

In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. This definition of a curve has been formalized in modern mathematics as: A curve is the image of an interval to a topological space by a continuous function.

**What is a continuous curve?**

A function is continuous when its graph is a single unbroken curve … that you could draw without lifting your pen from the paper.

**How do you know if an equation is continuous?**

Saying a function f is continuous when x=c is the same as saying that the function’s two-side limit at x=c exists and is equal to f(c).

### What is continuous in research?

Continuous research is about opening, building, and maintaining “a dialogue” with audiences of interest. Continuous research is undertaken to provide regular, ongoing data, information, and insights as opposed to ad hoc studies that are more project oriented and carried out at specific times for specific reasons.

**Which function is continuous across its domain?**

Definition. A function f is continuous on its domain D if f is continuous at every point c∈D. Example 1. The function f(x)=ex (with domain R) is continuous on its domain.

**How can we say every curve is function?**

A curve is a continuous function γ:I→X where I⊂R is an interval and X is a topological space. So, every curve is a function, but this does not means that, If X=R2 than any curve can be expressed as a function f:R→Ry=f(x).

#### What is continuous function in real analysis?

Definition. A function f : R→ R is said to be continuous at a point p ∈ R if whenever (an) is a real sequence converging to p, the sequence (f (an)) converges to f (p). Definition. A function f defined on a subset D of R is said to be continuous if it is continuous at every point p ∈ D. Example.

**Why research is a continuous process?**

The research process is a continuous cycle. Research does not follow a one-way linear progression, instead it is a continuous process of checking and re-checking, evaluating and analyzing, and repeating the entire process over and over again.

**Why are continuous variables rounded in statistical studies?**

Continuous variables need to be rounded because of the limits of the measuring device.

## How do you identify a curved line?

A curve is defined as a smoothly- flowing continuous line that has bent. It does not have any sharp turns. The way to identify the curve is that the line bends and changes its direction at least once. Curve Shape. Circles, ellipses, parabolas, and hyperbolas, as well as arcs, sectors and segments, are two-dimensional curved shapes.

**What type of curve has no endpoints?**

A curve has no endpoints, and when it encloses the region or area will form, it is known as the closed curve. The type of curve is formed by joining the two endpoints of the open curve. The best example of closed curves are circles, ellipses, etc.

**What is an algebraic curve with infinite set of solutions?**

Algebraic curves specified by an equation of the first degree are straight lines. An equation of the second degree that has an infinite set of solutions defines an ellipse, a hyperbola, a parabola, or a curve that splits into two straight lines (which may coincide).

### What is a curve in a plane?

In analytic geometry a curve in a plane is defined as a set of points whose coordinates satisfy an equation $ F ( x , y ) = 0 $.
