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

Answer:

A) $x = y^{2}$

Step-by-step 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.
