# Function/Curve that goes through certain points?

• Kepler_
In summary, a function or curve that goes through certain points is a mathematical representation of a relationship between variables. To find such a function/curve, the coordinates of the points are needed and can be found using various methods. There can be multiple functions/curves that go through the same set of points due to the infinite ways to represent a relationship between variables. Finding a function/curve that goes through certain points is significant as it allows for predictions and analysis of the relationship between variables. This has various real-world applications in fields such as physics, economics, and engineering.

Is there a simple way to make a function go through a set of points?

Something similar to what I'm looking for is this; a function that creates a smooth curve crossing y=0 at a list of x-coordinates

This will cross y=0 at x=-10, x=-2, and x=5
f(x)=(x-(-10))(x-(-2))(x-(5))

This is simple and infinitely expandable. Thanks!

## 1. What is a function/curve that goes through certain points?

A function or curve that goes through certain points is a mathematical representation of a relationship between two or more variables. The function is defined by a set of equations or rules that relate the input variables (independent variables) to the output variables (dependent variables). The function is able to pass through specific points because the values of the variables satisfy the equations or rules of the function.

## 2. How do you find a function/curve that goes through certain points?

To find a function/curve that goes through certain points, you need to know the coordinates of the points. Then, you can use a variety of methods such as substitution, elimination, or graphing to solve for the unknown variables in the equations. Once you have the equations, you can combine them to form a function or curve that passes through the given points.

## 3. Can there be multiple functions/curves that go through the same set of points?

Yes, there can be multiple functions/curves that go through the same set of points. This is because there are infinite ways to represent a relationship between variables. For example, a straight line and a parabola can both pass through the same two points, but they have different equations and therefore represent different functions/curves.

## 4. What is the significance of finding a function/curve that goes through certain points?

The significance of finding a function/curve that goes through certain points is that it allows us to make predictions and analyze the relationship between the variables. We can use the function/curve to determine the value of the dependent variable for a given value of the independent variable, or to find the relationship between the variables in a real-world scenario.

## 5. What are some real-world applications of finding a function/curve that goes through certain points?

There are many real-world applications of finding a function/curve that goes through certain points. For example, in physics, we use functions/curves to represent the relationship between distance and time in motion, or between force and distance in a spring. In economics, we use functions/curves to represent the relationship between supply and demand, or between cost and profit. Functions/curves are also used in engineering, biology, and many other fields to model and understand various phenomena.
