Exercise 6 Page 59

To graph the quadratic function given in intercept form $f(x)=a(x-p)(x-q),$ we must start by identifying the values of $a,$ $p,$ and $q.$ We can see that $a=\text{-}1,$ $p=\text{-}1,$ and $q=\text{-}5.$ Now, we will follow four steps to graph the function.

1. Identify the $x\text{-}$intercepts.
2. Plot the $x\text{-}$intercepts and find the axis of symmetry.
3. Calculate and plot the vertex.
4. Connect the points with a parabola.
