Determine whether an equation determines y as a functions of x

The video tutorial explains how to determine if equations represent functions of Y in terms of X. It emphasizes that a function must have a unique output for each input. The tutorial demonstrates solving equations to isolate Y and discusses the implications of taking square roots, which can result in multiple values for Y, thus affecting whether an equation can be considered a function.

What is the definition of a function in terms of X?

How can you determine if an equation represents a function?

Explain the significance of having a unique Y value for each X value in a function.

What happens when you take the square root of both sides of an equation?

Why can some equations not be written as a function of Y in terms of X?
