Question

what is the vertex of the quadratic equation y=-2x^2 + 4x – 6??

Answer 1

Use -b/2(a)

Answer 2

so, -4/-2(2)

Answer 3

Then once you get the value once you solves plug that number in for x and solve for y.

Answer 4

From @orphtroll, Vertex ( h, k ):
h = -b/2a = ....
-> k = f (1) = -2 + 4 – 6 = ...
