Answer:

third option down

Explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

• If a > 0 then graph opens up

• If a < 0 then graph opens down

y = - 2(x + 3)² - 1 ← is in vertex form

with vertex = (- 3, - 1 ) and a = - 2

thus graph has vertex at (- 3, - 1 ) and opens down

the graph fitting this description is third down
