Answer:
3400
Step-by-step explanation:
60 * 70 = 4200
70 - 10 - 20 = 40
20 * 40 = 800
4200 - 800 = 3400
Step-by-step explanation:
The equation given is of the form

where (h, k) are the coordinates of the vertex. So in this case, the vertex is located at (4, 2). Since a is a negative number (a = -3), this means that the vertex is a maximum because the parabola opens downward.
