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.
The first picture about the 2 3/4 the answer is c. think of how 4 quarters can make a dollar, 3/4 being 3 quarters out of a dollar, then you can ask yourself how much is 3 quarters (.75) and with 2 being a whole it would leave you with 2.75 being equivalent to 2 3/4 <span />
To find the area of the rectangle, you have to multiply the length by the width. 27 x 40 = 1,080 in ^2
