- $f ( x ) = - 2 x ^ { 2 } + 24 x - 70$

• A) Vertex: \(( - 6,2 )\); \(x\)-intercepts: \(( - 5,0 )\) and \(( - 7,0 )\); y-intercept: \(( 0 , - 70 )\)
• B) Vertex: \(( - 2 , - 6 )\); \(x\)-intercepts: none; y-intercept: \(( 0 , - 70 )\)
• C) Vertex: \(( 6,6 )\); \(x\)-intercepts: \(( 6 \pm \sqrt { 3 } , 0 )\); y-intercept: \(( 0 , - 70 )\)
• D) Vertex: \(( 6,2 )\); \(x\)-intercepts: \(( 5,0 )\) and \(( 7,0 )\); \(y\)-intercept: \(( 0 , - 70 )\)
