This one is factorable, making roots easy to find, and making the axis easy to find also.
, so the x-intercepts are x=-3 and x=4. That means, two points of the graph are (+3,0) and (-4,0).
The vertex occurs at . We only then need to feed to f(x) and find the resulting value. is this value.
You may then plug in a couple of more points if you want to help show the shape a little better.
