Question

Where is the vertex of the parabola?



y = x^2 + 2x + 3









A.

Above the x-axis








B.

On the y-axis








C.

On the x-axis








D.

Below the x-axis

Answer 1

A?

Answer 2

\[ y = x^2 + 2x + 3 \] vertex is at \(x=-\frac{b}{2a}=-\frac{2}{2}=-1\) for the first coordinate

Answer 3

the second coordinate is \((-1)^2+2(-1)+3=2\) making the vertex \((1,2)\) which is evidently above the \(x\) axis

Answer 4

so yeah, A
