$\text{Number of $x-$intercepts: } 0 \\\text{Number of $y-$intercepts: } 1$

For a parabola that opens $\text{ down }$ and whose vertex is located at $\text{ QIV }$ (such as the example shown below), then the parabola has the following characteristics: \begin{array}{l}\require{cancel} \text{Number of $x-$intercepts: } 0 \\\text{Number of $y-$intercepts: } 1 .\end{array}
