MULTIPLE CHOICE QUESTION Parabola: y = x2 + 4x - 5 Which parabola will open downward when graphed? Green Red Parabola: y=-x2+x+6​

Answer 1

green one

Explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

• If a > 0 then the graph opens upwards

• If a < 0 then the graph opens downwards

y = - x² + x + 6 , has a = - 1 < 0

Then its graph will open downwards
