Y= -2x²-3x+2, (form y = ax² +b .x + c
The parabola opens downward & hence it's Vertex is a MAXIMUM.
We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125
Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
For the given question above, if you divide the 4 pizzas up between the 8 people you get the fraction 4/8. So this is TRUE.
<span>You then reduce the fraction by a common factor (in this case 2), giving you 1/2. </span><span>So each person gets 1/2 of a pizza. </span>
