What is a definition of an independent and dependent variable???



Thanks for your help!!What is a simple definition of a dependent and independent variable?
An independent variable is an "input" variable. It's usually something you can control.



A dependent variable is an "output" variable. It's usually something that you measure.



For instance:



f(x) = y = x虏



You can think of x as the independent variable and y as the dependent variable, because the value of y depends on the value of x. That is, you can plug in a value for x, and you get a value back out for y.



Plug in x = 1:



f(1) = 1虏 = 1



And you get out y = 1.



Plug in x = -2:



f(-2) = (-2)虏 = 4



And you get out y = 4.What is a simple definition of a dependent and independent variable?
a dependent variable is something that depends on another thing



and an independent variable is something that doesn't depend on anything...



like.... y = 2x + 4



y is dependent on x...because as x changes y changes..... ( in general term of graphing )



therefore.....since y is dependent ... then x is independent :)What is a simple definition of a dependent and independent variable?
An independent variable is one that can take any value you choose, maybe within certain limits. A dependent variable is one that is worked out from some formula or process.
