Sketch the graph of the quadratic function $f(x) = - x^2 -5 x -6$ by hand.
Indicate on your sketch the coordinates of any turning points and of
any point where the graph crosses the $x$ or $y$ axis.
Your graph should look something like this.
Roots are $x = -3.00$ and $x = -2.00$.
There is a maximum point at $x=-2.50$, $y=0.25$
The graph intercepts the $y$-axis at $y=-6$
