12-73.

On graph paper, make a table and graph the function $f(x) = −2(x − 1)^2 + 8$.

Make sure to make a table of points.

1. Label the $x$- and $y$-intercepts and state their coordinates.

Where does the graph cross the $x$-axis? The $y$-axis?

2. Name the vertex.

$(1, 8)$

3. Find $f(100)$ and $f(−15)$.

Substitute these values into the equation.
