Applying the completing square method:
f(x) = 2x² - 8x + 6
Dividing by a
f(x) = 2(x² - 4x + 3)
Adding and subtracting the square of b (which is 2 in this case)
f(x) = 2(x² + 2² - 4x -2² + 3)
f(x) = 2(x - 2)² - 2
The vertex is (2, -2) and it is a minimum since the coefficient of x is positive.
The answer is B.

Answer:
a.) 1/3
