Question

MEDAL
Using the completing-the-square method, find the vertex of the function f(x) = –3x^2 + 6x − 2 and indicate whether it is a minimum or a maximum and at what point

Answer 1

For minimum or maximum just differentiate it.

Answer 2

you are going to put the thing in a form y = a( x - h)^2 + k
by completing the square..

Answer 3

Maximum at (1,1)

Answer 4

for vertex Apply x=-b/2a

Answer 5

min (1,1)

Answer 6

-6/-3(2)=1

Answer 7

do you have to show the completing the square work?

Answer 8

know just min and max and what point

Answer 9

So you dont need the way... okay i will give you max/min

Answer 10

i am pretty sure it is min but i don't know the coordinates

Answer 11

Yes it is minima, it is (-1,-5)..

Answer 12

you have the wrong coordinates
