How do you find the equation of a function?

It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

What is an equation in math?

An equation says that two things are equal. It will have an equals sign “=” like this: 7 + 2 = 10 − 1. That equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1) So an equation is like a statement “this equals that”

What are the 3 types of equations?

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

Which is not a function?

Horizontal lines are functions that have a range that is a single value. Vertical lines are not functions. The equations y = ± x and x 2 + y 2 = 9 are examples of non-functions because there is at least one -value with two or more -values.

How do you know if a function is not a function?

Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

Ideal gas equation with density

What is the density of an ideal gas? The term ideal gas refers to a hypothetical gas composed of molecules which follow a few rules: Ideal gas molecules do not attract or repel each other. The only interaction between ideal gas molecules would be an elastic collision upon impact with each other or an elastic […]

Equation for falling object

What is the equation for free fall? Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. Velocity is defined as gravity x […]
