Question

Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1

Answer 1

A)
`x = y^(2)`

Explanation:

An equation is a function of
`x` when
`x` is the independent variable, that is:

`y = f(x)` (1)

Where
`y` is the dependent variable.

According to this,
`x = y^(2)` does not represent a function of
`x`, since the independent variable is a function of
`y`, that is,
`x = f(y)`. Therefore, the correct answer is A.
