Question 8 of 10

Find the vertex of a quadratic function.

\( \text{Find the vertex of the quadratic function } y = 2x^2 - 8x + 6. \)

Choose one option:

Compute axis of symmetry then calculate the y-coordinate.

Use \(x = -b/(2a)\) to find the x-coordinate and substitute into \(y = ax^2 + bx + c\) to find y.
