Graph $y=x^2-8x+7$ and fully describe it.

Make a table. Use integers from $−1$ to $9$ for your inputs.

The $x\text{-intercepts}$ are where the graph intersects the
$x\text{-axis}$, or where $y=0$.

The $y\text{-intercept}$ is where the graph intersects the $y\text{-axis}$, or where $x=0$.

The vertex is the lowest or highest point on the parabola.

Parabola opening upward.
