5-43.

Based on the tables below, what are the $x$- and $y$-intercepts of the corresponding graphs? Use the fact that the relationship shown in the table in part (b) is quadratic to write an equation to represent the relationship.

1.  $x$ $y$ $3$ $0$ $0$ $16$ $–5$ $0$ $–1$ $–8$ $6$ $22$ $3$ $0$
1.  $x$ $y$ $7$ –27 $1$ $0$ $10$ $–67.5$ $0$ $–2.5$ $2.5$ $0$ $–7$ $–76$
1.  $x$ $y$ $0$ $–16$ $–5$ $11$ $3$ $–2$ $8$ $0$ $13$ $27$ $–6$ $14$

The $x$-intercept occurs when $y = 0$ and the $y$-intercept occurs when $x = 0$.
