Question

What is the axis of symmetry for the function? y = x2 + 3x - 4


y = -2


y = -1.5


x = -2


x = -1.5

Answer 1

-b/2a

Answer 2

\[x=\frac{-b}{2a}=\frac{-3}{2}\]

Answer 3

@Merts I don't know what that meant.

Answer 4

What is the equation for a quadratic in standard form?

Answer 5

at the axis passing through the vertex.

compare with this equation y = ax^2+bx+c

Answer 6

The x coordinate of the vertex of a parabola is found by using the formula x = -b/2a
