Question

If $y$ is expressed in terms of a variable $x$ as $y=f\left(x\right)$ then $y$ is called_____

Answer 1

Define $y$ in $y=f\left(x\right)$:

The given expression is $y=f\left(x\right)$.

Here we can see that $x$ is an independent variable since the value of $x$ can be any rational or irrational number.

We can evaluate $y$ when a function is applied to it.

Therefore, $y$ is the respective output when the function is applied to a particular value of $x$.

Hence, $y$ is called the output.
