Yo

#

The minimum is the lowest y value

#

that’s when the bracket =0

#

So the y coord is -18

#

And u gotta find the x coord when the bracket is 0

#

which is x=4

#

(4,-18)

mossy crystal please help i dont understand

(4,-18) you just flip the x coord sign and keep the y

#

minimum would be for + quadratic
max for - quadratic
