You can put this solution on YOUR website! difference between equation
and funtion?
-------------
An equation states that 2 quantities are equal.
----
A function performs an operation - it processes the input and produces an output.
You can put this solution on YOUR website! a function is a special kind of equation where there is only one value of y for each and every value of x.
an example of a function is y = x + 6
for each value of x, there is one and only one value of y.
an example of an equation that would not be a function is called a relation.
an example of a relation is y = +/- sqrt(x)
in this equation, each and every value of x will have 2 values of y.
one of them for + sqrt(x) and one of them for - sqrt(x).
you do not need to have more than one value of y for each and every value value of x.
if only one of the values of x has more than one value of y, then the equation is a relation and not a function.
to be a function, each and every value of x has to have one and only one corresponding value of y.
if any value of x has more than one value of y, then the equation is a relation and not a function.
here's a link that talks about functions and relations.
it's a good link so pay attention if you want to learn more about the difference between them.
there are more than one page in the tutorial, so please view all the pages if you want a complete explanation with all the little nuances that can occur.
