Answer:
True
Step-by-step explanation:
Given a parabola in vertex form
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then the graph opens up
• If a < 0 then the graph opens down
Given
f(x) = - (x + 3)² + 2 ← in vertex form
with a = - 1 < 0 then graph opens down is True
