Question

Graph the function. Identify the vertex and axis of symmetry.

f(x) = x2 +4x – 2 (1 point)

Answer 1

how come when i do these i never get the one point?

Answer 2

the first coordinate of the vertex is always \(-\frac{b}{2a}\) which in your case is
\[-\frac{4}{2\times 1}=-2\]

Answer 3

the second coordinate of the vertex is what you get for \(y\) when you replace \(x\) by \(-2\)
