Answer:
Examples : y is a function of x, x is a function
of y. : y is not a function of x (x = 3 has multiple outputs),
X is a function of y: y is a function of x, x is not a function of y (y = 9 has multiple outputs).
What is an example of not a function?
Vertical lines are not functions. The equations y = ± x and x 2 + y 2= 9 are examples of non-functions because there is at least one-value with two or more - values.
