Determine whether the equation defines y as a function of x.
-$$y = \sqrt { - 6 x + 5 }$$
A) $y$ is a function of $x$
B) $y$ is not a function of $x$

Question

Quizplus · Accepted Answer

The equation defines $y$ as a function of $x$ because for each value of $x$ that makes the expression under the square root non-negative ($-6x + 5 \geq 0$), there is exactly one corresponding value of $y$. This satisfies the definition of a function, where each input has exactly one output.
