Question

Identify the vertex for the graph of y = −3x2 + 6x − 4.

Answer 1

y = −3x2 + 6x − 4.
y = −3x2 + 6x − 3-1 .
y=-3(x^2-2x+1) -1
y+1=-3(x-1)^2
clearly the vertex is (1,-1)

Answer 2

ok thanks

Answer 3

In these types of sums first try to complete the squares or the cube as the case may be and then use suitable transformation (translation of origin)
