What does y mean in Math?

In math, $y$ is generally used as an unknown variable. we use $y$ as a variable just like $x$ .

$x$ is also used as a variable in Algebra

‘ $y$ ‘ holds the place of a number that we may not know just yet in pre-algebra. We use this symbol when we don’t know how many we have of something or when the number of them can change.

$y + 4$ means we add $4$ to whatever we decide $y$ stands for. $y$ could be any number, so we’re just holding its place with the variable

Why are X and Y used in Algebra?

In short, it is the $English$ (or Latin) version of the Greek letter $χ$ (chi), which was the first letter of the transliteration of the Arabic word for ‘something’, which was used in the original algebra texts. Since $x$ was commonly used for one unknown, it made sense to use $y$ as a second, and $z$ as a third unknown.

What does y=y(x) Mean?

In Algebra $y$ is a variable we use $y$ in different ways, mostly an unknown variable.

If we write $y=y\left(x\right)$ .It means $y$ is a dependent variable and depends on x. We may also called $y=y\left(x\right)$ a function.

we mostly use this function in calculus and Analytical geometry.
