2.) Find the vertex only for the following function:
y = -3x^2 + 12x - 5

( 1 ) Find by using a formula of (-b/2a, (4ac-b²)/4a)

The vertex is at (2,7)

( 2 ) Find by using a derivative (Calculus)

You can also find a vertex by using a calculus. Using a derivative

Then substitute y' = 0 to get a vertex.

Then substitute x = 2 in the equation of y = -3x²+12x-5

x = 2 and y = 7, therefore. The vertex is (2,7)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
