question 57

Multiple Choice

Find the vertex, the y-intercept, and the x-intercepts (if any exist) , and graph the function.
- $$f ( x ) = - x ^ { 2 } - 2 x + 8$$

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