Question 10 of 10

Find the vertex of a quadratic function.

‹

\( \text{Find the vertex of the quadratic function } y = x^2 + 4x + 3. \)

Choose one option:

Compute axis of symmetry, then calculate the corresponding y-coordinate.

The vertex is \((x, y)\) using \(x = -b/(2a)\) and substituting to get y.
