## Is there an equation for every curve?

Does any curve I draw on a graph have an equation? So your curve can be approximated as accurately as you wish, as Adhithya described. However, if you change the question to, “Given any continuous function, will it always have an equation?”, then the answer is no.

## Does every function have an equation?

A function is a set of ordered pairs where each input (x-value) relates to only one output (y-value). A function may or may not be an equation. Equations are functions if they meet the definition of a function. Aren’t all functions also equations since functions contain an = sign (e.g f(x)=x+2x).

## What is the equation of a parabola?

Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y – mx – b)^2 / (m^2 +1) = (x – h)^2 + (y – k)^2.

## How do you cut a graph?

Cut Set of a Graph Let ‘G’= (V, E) be a connected graph. A subset E’ of E is called a cut set of G if deletion of all the edges of E’ from G makes G disconnect. If deleting a certain number of edges from a graph makes it disconnected, then those deleted edges are called the cut set of the graph.

#### Equation of vertical line

How do you write an equation for a vertical and horizontal line? Horizontal lines go left and right and are in the form of y = b where b represents the y intercept. Vertical lines go up and down and are in the form of x = a where a represents the shared x coordinate […]

#### Bernoulli’s equation example

What does Bernoulli’s equation State? Bernoulli’s principle states the following, Bernoulli’s principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed. Why is Bernoulli’s equation used? The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one […]
