Question 1 of 10

Find the axis of symmetry of a quadratic function.

›

\( \text{Find the axis of symmetry for the quadratic function } y = 2x^2 - 12x + 18. \)

Choose one option:

Use \(x = -b/(2a)\) to compute the vertical line of symmetry.

The axis of symmetry formula is \(x = -b/(2a)\) for \(y = ax^2 + bx + c\).
