Use the following information to answer questions 55-57.
Consider the set of all points (x,y) that satisfy all 3 of the conditions below:
y ≥ 0
y ≤ 2x + 4
y ≤ -x + 4
The graph of this set is △ABC and its interior, which is shown shaded in the standard(x,y) coordinate plane below. Let this set be the domain of the function P(x,y) = 4x + 3y.
56. The quadrants of the standard(x,y) coordinate plane are labeled in the figure below. The domain of P(x,y) contains points in which quadrants?
Your Answer is
Correct Answer is F
Explanation
According to the image given at the beginning, all points have non-negative vertical coordinates and positive or negative horizontal coordinates, so they should be in the first and second quadrants. Therefore choose F.
