Answer
$25$, $-5$, $5$, $(-5,0)$, $(5,0)$.
$ 9$, $-3$, $3$, $(0,-3)$, $(0,3)$.
Work Step by Step
From the given equation, we can identify $a^2=25$; thus $a=5$ and the vertices on the x-axis, or the x-intercepts are $-5$ and $5$. The vertices are $(-5,0)$ and $(5,0)$.
From the given equation, we can identify $b^2=9$; thus $b=3$ and the y-intercepts are $-3$ and $3$ indicating that the graph passes through $(0,-3)$ and $(0,3)$.
