Question

any1 know how to tell independent and dependent variables in MATH

Answer 1

The independent variable, otherwise statistically known as the explanatory variable, is usually depicted by X, and represents the mathematical "input" value(s) to a function. Essentially, it's what you put into a function.

The dependent variable, otherwise statistically known as the response variable, is usually depicted by Y, and represents the mathematical "output" value(s) to a function. Essentially, it's what you get out of a function.

The independent variable and dependent variable are directly associated at all times: for a simple, continuous, defined function, you should be able to get a single value of Y for each X-value you put in.

For example, if a function dictates that for each value you put in, you will get three times that value out in return. This can be described by Y = 3X. This works in all scenarios. If you put in 3 amounts of something into the function, you should expect to get 9 amounts of it back out. Likewise, when X = 3, Y = 9 because Y = 3(3).

Hope that helps.
