Conversation so far:
what is the meaning of x and y in math
In math, x and y represent variables
give an example of x and y in math.
An example of using x and y is: 𝑦=𝑎𝑥2+𝑏, where a and b are constants.
are there specific kinds of variables?
Dependent and independent variables are two types of variables.
what is the difference between a dependent and independent variable symbols?
A symbol that stands for an arbitrary input is called an independent variable (x), while a symbol that stands for an arbitrary output is called a dependent variable (y).

Question: give an example.
Self-contained rewrite: give an example of independent and dependent variables.
