Graph the Function $f ( x ) = 3 x ^ { 2 } - 12 x + 8$

question 181

Multiple Choice

Graph the function. Identify the vertex, x-intercepts, and the equation for the axis of symmetry.
- $f ( x ) = 3 x ^ { 2 } - 12 x + 8$

• A) vertex: \(( - 4,2 )\) \(\mathrm { x }\)-intercepts: none axis of symmetry: \(x = - 4\)
• B) vertex: \(( - 2 , - 4 )\) \(x\)-intercepts: \(\left( - \frac { 6 \pm 2 \sqrt { 3 } } { 3 } , 0 \right)\) axis of symmetry: \(x = - 2\)
• C) vertex: \(( 2 , - 4 )\) \(x\)-intercepts: \(\left( \frac { 6 \pm 2 \sqrt { 3 } } { 3 } , 0 \right)\) axis of symmetry: \(x = 2\)
• D) vertex: \(( - 3 , - 2 )\) \(x\)-intercepts: \(( - 3 \pm 2 \sqrt { 2 } )\) axis of symmetry: \(x = - 3\)
