Answer
x-intercepts: none.
y-intercept: $-\displaystyle \frac{1}{2}.$
Work Step by Step
The y- intercept is the value $r(0)$, if defined.
$r(0)=\displaystyle \frac{2}{0+0-4}=-\frac{1}{2}$
The x intercepts are values of x where $r(x)=0.$
$r(x)=0$ occurs when the numerator equals 0.
The numerator is zero when
$ 2=0\quad$
This never occurs, so there are no x-intercepts.
