Answer:
What is OBJ X = -81
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Rearrange slightly like so...
x^3-3x-5x^2+15 now factor first and second pair of terms...
x(x^2-3)-5(x^2-3)
(x-5)(x^2-3)
(x-5)(x-√3)(x+√3)
is a quadratic function, so its graph is a parabola.
Notice that the coefficient of x is 0, this always means that the axis of symmetry is the y-axis.
That is, the vertex of the parabola is in the y-axis, so the x-coordinate of the vertex is 0.
for x=0, y=-1. So the vertex is (0, -1)
The coefficient of
is negative. This means that the parabola opens downwards, so the vertex is a maximum.
Answer: (0, -1) , maximum (none of the choices)

Required
Which of the given options has the highest interest rate
To do this, we have to list out the interest rates of each of the given accounts:

- The interest rate on money market account is between 0.30% and 0.50% APY.
- The interest rate on checking account is between 0.06% and 0.09% APY.
- The interest rate on Certificate of Deposit is between 0.55% and 0.80% APY.
So, by comparison:
