Graph the Function $f ( x ) = x ^ { 2 } - 5 x + 1$

question 184

Multiple Choice

Graph the function. Identify the vertex, x-intercepts, and the equation for the axis of symmetry.
- $f ( x ) = x ^ { 2 } - 5 x + 1$

• A) vertex: \(\left( \frac { 5 } { 2 } , - 5 \frac { 1 } { 4 } \right)\) \(x\)-intercepts: \(\left( \frac { 5 \pm \sqrt { 21 } } { 2 } , 0 \right)\) axis of symmetry: \(x = \frac { 5 } { 2 }\)
• B) vertex: \(( 0,1 )\) \(\mathrm { x }\)-intercepts: none axis of symmetry: \(x = 0\)
• C) vertex: \(( 2 , - 9 )\) \(x\)-intercepts: \(( - 1,0 )\) and \(( 5,0 )\) axis of symmetry: \(\mathrm { x } = 2\)
• D) vertex: \(\left( - \frac { 5 } { 2 } , - 5 \frac { 1 } { 4 } \right)\) x-intercepts: \(\left( \frac { - 5 \pm \sqrt { 21 } } { 2 } , 0 \right)\) axis of symmetry: \(x = - \frac { 5 } { 2 }\)
