Question

Does y= -5x2 + 3x – 6 open upward or downward?
O Upward
O Downward

Answer 1

DOWNWARDS because that’s the answer lol

Answer 2

downwards

Explanation:

Given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

• If a > 0 then opens upwards

• If a < 0 then opens downwards

y = - 5x² + 3x - 6 ← is in standard form

with a = - 5 < 0 then graph opens downwards
