Question

y = 2x2 + 8x − 3

y = −2x2 + 8x − 3

y = 2x2 − 8x − 3

y = −2x2 − 8x − 3

Answer 1

UGH

Answer 2

i guess it's an upside down parabola so it's C or D (because of the negative coefficient of x^2)

Answer 3

D.

Answer 4

the x coordinate of the vertex is -b/(2a) and has to be negative (it's shown in the second quadrant)

Answer 5

yep...
