Question

The equation for a parabola that opens upward and has a vertex in the second quadrant is given by y=a(x-b)^2+c. Choose all of the conditions below that would apply to this equation. a. a<0 b. a>0 c. b<0 d. b>0 e. c<0 f. c>0

parthkohli · Answer

If a is positive, then it opens upward.
If a is negative, then it opens downwards.

ash2326 · Answer

a decides whether parabola will open up or downwards
a>0 parabola open up
a<0 parabola open downwards
vertex is (b, c)
Can you tell the conditions for b and c?
