[brazen grail]

you have 2 points given

draw them in

[brazen grail]

bruh if you dont even know how to draw points into a coordinate system, you wont understand any of this stuff

look, your 2 given points are (-3|6), which is a maximum and (1|-30) which is a minimum

and when you look at the function itself you can clearly see the 3 roots of it
