Determine whether the equation defines y as a function of x.
-$$y ^ { 2 } = 3 x$$
A) $y$ is a function of $x$
B) $y$ is not $a$ function of $x$

Question

Quizplus · Accepted Answer

For a given value of $x$, the equation $y^2 = 3x$ can produce two values of $y$ (one positive and one negative), meaning a single input $x$ can result in more than one output $y$. This violates the definition of a function, which requires each input to have exactly one output.
