1. The problem asks for the y-intercept of the given parabola. 2. The y-intercept is the point where the graph crosses the y-axis. This happens when $x=0$. 3. From the graph description, the parabola crosses the y-axis at $y=6$. 4. Therefore, the y-intercept is the point $(0,6)$. 5. In summary, the y-intercept is the value of $y$ when $x=0$, which is $6$ in this case.
