question 95

Multiple Choice

- $$f ( x ) = x ^ { 2 } + 2 x - 8$$

• A) Vertex \(( - 1 , - 9 )\); \(x\)-int \(= ( - 4,0 )\) and \(( 2,0 )\); \(y\)-int \(= ( 0 , - 8 )\)
• B) Vertex \(( 1 , - 9 )\); \(x\)-int \(= ( - 2,0 )\) and \(( 4,0 )\); \(y\)-int \(= ( 0 , - 8 )\)
• C) Vertex \(( 1 , - 9 )\); \(x\)-int \(= ( - 2,0 )\) and \(( 4,0 )\); \(\mathrm { y }\)-int \(= ( 0 , - 8 )\)
• D) Vertex \(( - 1 , - 9 )\); \(x\)-int \(= ( 4,0 )\) and \(( 2,0 )\); \(y\)-int \(= ( 0,8 )\)
