Consider: \[-2x ^{2}+4x -1\]

OpenStudy (anonymous):

1.) This equation is given in: (A) Standard form (B) Vertex form (C) Intercept form (D) No particular form

OpenStudy (anonymous):

2.) This parabola opens: (A) upward (B) right (C) downward (D) left

Directrix (directrix):

The algebraic expression you posted is not an equation. Is there a y supposed to be with it?

OpenStudy (anonymous):

3.) This parabola will have (A) a maximum (B) a minimum (C) neither a maximum or a minimum

OpenStudy (anonymous):

4.) This axis of symmetry is (A) x=4 (B) x=-2 (C) x=1 (D) x=-1

OpenStudy (anonymous):

@directrix Sorry. It's y=-2x^2+4x-1

OpenStudy (anonymous):

My answers: 1.) A 2.) B 3.) B 4.) C

OpenStudy (perl):

y = ax^2 + bx + c is called standard form y = a ( x - h)^2 + k is called vertex form y = a ( x - r1) ( x - r2) is called intercept form

OpenStudy (perl):

so your equation looks closest to which form?

OpenStudy (anonymous):

Standard form?

OpenStudy (perl):

yes
