In function notation, the variable used for output is typically denoted as \( y \) in the context of the function \( f(x) = y \). Here, \( x \) is the input variable, and \( y \) is the output variable or the value of the function for that particular input.
For example:
- If you have a function defined as \( f(x) = 2x + 3 \), when you input a specific value for \( x \) (say \( x = 2 \)), the output \( y \) would be \( f(2) = 2(2) + 3 = 7 \).
So, in summary:
- Input: \( x \)
- Output: \( y \) (typically associated with the function value)
However, you can make the output notation different if you prefer, but \( f(x) \) usually means output \( y \) in standard function notation.
