A function tries to define these relationsips. It tries to give the relationship a mathematical form. An equation is a mathematical way of looking at the relationship between concepts or items. These concepts or items ar represented by what are called variables.

When is a linear equation an identity?
When the equation represents a horizontal line.
Is x2 plus 8 a function?
x2+8= y This equation represents a function. It will be a parabola with the vertex at (0,8). You can easily graph this on a graphing calculator or from prior knowledge. You know the basic graph of y=x2 with vertex (0,0) and opens upwards on the y-axis. From the equation, you simply shift the vertex vertically up 8 so the new vertex is (0,8) This represents a function because for every x value there is one y value.
What are the functions of a line?
f(x) = mx + bRestate the question: What are the functions that can represent a straight line?The equation y=mx + b represents all straight lines except for a vertical line, which has undefined slope.In function form, this is f(x) = mx + b. m represents the slope, and b the y-intercept.x = a represents a vertical line, which is not a function.The 'general form' of the straight line equation is Ax +By + C = 0. As long as B is not zero, this is a function.
Write a function represents the line that contains the point 2 and 12 and has a slope of-3?
As a straight line equation: y = -3x+18 in slope intercept form
What is thedifrent betweena quadratic equation and a quadratic function?
An equation just has an equal sign. A function is basically just an equation without one!
Does the equation y equals 2x plus 1 represent a function?
The [ 2x + 1 ] represents a function of 'y' .
How do you determine if a relation represents a function?
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
What are uses of derivatives?
A derivative of a function represents that equation's slope at any given point on its graph.
What are the uses of derivatives?
A derivative of a function represents that equation's slope at any given point on its graph.
What is the equation f?
The letter f represents function notation, and replaces y as a variable. f(x)=ax+b is a linear function.
Why f represents the graph of a function?
Because f represents a function.
How can the equation force massx acceleration be rewritten?
The equation can be rewritten as F = ma, where F represents force, m represents mass, and a represents acceleration.
Which equation below represents the inverse function Mp?
It might have been possible to answer the question if you had bothered to include any equations below. But since you haven't there can be no answer.
When is a linear equation an identity?
When the equation represents a horizontal line.
Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
What capital letter represents this equation after it has been correctly balanced?
The capital letter "C" represents the balanced chemical equation.
What variable represents thermal energy in the equation QmcT?
The variable "Q" represents thermal energy in the equation Q=mcΔT.
