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
Answer:
Where's the geometric sequence?
Answer:
Step-by-step explanation:
-7x+4=18
-7x=14
Divide-7 on both sides of the equal sign which is going to leave you with x=-2
