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)
89300, 94300, 99300, 104300, 109300. To keep going forward, add 5000 after each number.
First let's calculate the profit in the deal, subtracting the market value and the selling value:
So the profit is $55,000.
Now, calculating the fee of 10% of the profit, we have:
So the fee is $5,500, therefore the correct option is the fourth one.
Factor 3x^3-10x^2+3x+10
=(x-2)(3x^2-4x-5)
