Graph the Function $f ( x ) = x ^ { 2 } - 1$

question 119

Multiple Choice

Graph the function. Identify the vertex, x-intercepts, and the equation for the axis of symmetry.
- $f ( x ) = x ^ { 2 } - 1$

• A) vertex: \(( 0 , - 1 )\) \(x\)-intercepts: none axis of symmetry: \(x = 0\)
• B) vertex: \(( - 1,0 )\) x-intercept: \(( - 1,0 )\) axis of symmetry: \(\mathrm { x } = - 1\)
• C) vertex: \(( 0 , - 1 )\) \(x\)-intercepts: \(( - 1,0 )\) and \(( 1,0 )\) axis of symmetry: \(\mathrm { x } = 0\)
• D) vertex: \(( 0,1 )\) \(\mathrm { x }\)-intercepts: none axis of symmetry: \(x = 0\)
