question 129

Multiple Choice

An equation of a parabola $( y - k ) ^ { 2 } = 4 p ( x - h )$ is given. Graph the parabola. Write the equation for the directrix and axis of symmetry.
- $$( y - 1 ) ^ { 2 } = 12 ( x - 2 )$$

• A) directrix: \(x = - 1\); axis of symmetry: \(y = 1\)
• B) directrix: \(y = - 4\); axis of symmetry: \(x = - 2\)
• C) directrix: \(y = - 2\); axis of symmetry: \(x = 2\)
• D) directrix: \(x = - 5\); axis of symmetry: \(y = - 1\)
