An equation is a function if it is in y=mx+b form or has a y= in foront of it. f(x) is a classic way of writing a function.

Ex) X^2 is a function

Do you even know what a function is, stupid. A function is an equation that passes the vertical line test. go graph it bitc h

No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.

You need to know the domain first. For each value in the domain there will be a value for the function (or expression). These may not all be different. The set of these values is the range of the equation.

Any equation which maps each value of x in the domain to a value in the range is a function of x.

A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.

Y = X2 ===== This is a parabolic function because it passes the vertical line test. ( you should know what that test is )

A linear function has and x and a y and neither one is raised to a power other than 1.

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.

a function rule

If you know some values, then you at least have a function of some sort, but you don't know what other values might be. To be a useful function you must be aware that a rule exists to calculate its value for any situation, and preferably know what the rule (equation or whatever) is.

The set of all values of x, for which the equation is true is the domain of the function defined by that equation.

An equation just has an equal sign. A function is basically just an equation without one!
