Answer
The given equation defines $y$ as a function of $x$.
Work Step by Step
An equation defines $y$ as a function of $x$ if for every value of $x$, the equation gives only one corresponding value of $y$.
Note that the given equation gives one value of y-value for each value of $x$.
Example:
When $x=0$:
$y=2x^2-3x+4
\\y=2(0^2)-3(0)+4
\\y=0+4
\\y=4$
There is only one corresponding y-value for each value of $x$.
Therefore, the given equation defines $y$ as a function of $x$.
