Answer:

D) Vertex: (-2,-8); maximum

Step-by-step explanation:

y = -2x² - 8x - 16

The negative on the first term tells us that the vertex will be a maximum

vertex occurs when the derivative is set to zero

y' = -4x - 8

0 = -4x - 8

8 = -4x

x = -2

y = -2(-2)² - 8(-2) - 16

y = -8 + 16 - 16 = -8

poizon [28]

Let present value = P
interest rate, i = 0.06
time = 2 years
interest amount = 750
then
750 = Pin = P(0.06*2)
Solve for P
P=750/(0.06*2) = $6250
