A function is a rule to calculate a variable, based on one or more other variables. It may be written as an equation, but unlike a generic equation, in a function, for every value of the input variables, it may ONLY have ONE result.

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!
Is there an instance that a linear equation is not a function?
There is one form of linear equation that is not a function, and that is when x = c, where c is a constant.
When do you say that the equation is a function or not?
i may only be 10 yrs old but i can say that an equation is not an function like the graphs of quadratic functions you will only be given an equation
What equation describes the cosine function for a right triangle?
mathematical equation
How does the slope of a linear equation differ from the slope of a quadratic equation?
i dont know 8x+5y=89
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.
An equation that describes a function?
a function rule
Is a linear equation the same as a function?
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.
If a function is defined by an equation explain how to find its domain.?
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
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!
What is the equation of a logarithmic equation?
A logarithmic equation would be any equation that includes the log function.
Is the equation for a circle a function?
The equation for a circle is a function in that it can be graphed and charted. One common equation is x^2 + y^2 = r^2.
Is there an instance that a linear equation is not a function?
There is one form of linear equation that is not a function, and that is when x = c, where c is a constant.
Do a linear equation and a function share the same definition?
No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.
When do you say that the equation is a function or not?
i may only be 10 yrs old but i can say that an equation is not an function like the graphs of quadratic functions you will only be given an equation
If the equation of a function is a rational expression the function is rational?
True
How do you know if an equation is a function or not?
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
