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

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: $( - 1,0 )$ and $( 1,0 )$
axis of symmetry: $\mathrm { x } = 0$
B)

vertex: $( 1,0 )$
$\mathrm { x }$ -intercept: $( 1,0 )$
axis of symmetry: $\mathrm { x } = 1$
C)

vertex: $( 0,1 )$
$x$ -intercepts: none
axis of symmetry: $x = 0$
D)

vertex: $( 0,1 )$
$x$ -intercepts: $( - 1,0 )$ and $( 1,0 )$
axis of symmetry: $\mathrm { x } = 0$
