question 231

Multiple Choice

Identify the vertex, axis of symmetry, and intercepts for the graph of the function.
- $$g ( x ) = x ^ { 2 } - 2 x - 15$$

• A) Vertex at \(( - 1 , - 12 )\); axis: \(y = - 12 ; x\)-intercepts: \(( - 3,0 )\) and \(( 5,0 ) ; y\)-intercept: \(( 0 , - 15 )\)
• B) Vertex at \(( - 1 , - 12 )\); axis: \(x = - 1 ; x\)-intercepts: none; \(y\)-intercept: \(( - 3,0 )\)
• C) Vertex at \(( 1 , - 16 )\); axis: \(x = 1 ; x\)-intercepts: \(( - 3,0 )\) and \(( 5,0 ) ; y\)-intercept: \(( 0 , - 15 )\)
• D) Vertex at \(( 1 , - 16 )\); axis: \(y = - 16 ; x\)-intercepts: none; \(y\)-intercept: \(( - 3,0 )\)
