4-97.

On graph paper, use a table to make a complete graph of $y=x^2−2x−8$.

1. Write the coordinates of the $y\text{-intercept}$. What is the connection between the $y\text{-intercept}$ and the equation $y=x^2−2x−8$?

It is the constant term in the equation.

2. Write the coordinates of the $x\text{-intercepts}$.

3. What is the lowest point on the graph?

Where is the vertex of your graph?
