Multiple Choice

Solve the problem.
-Let $P = ( x , y )$ be a point on the graph of $y = \sqrt { x }$ . Express the distance $d$ from $P$ to the point $( 1,0 )$ as a function of $x$

A) $d ( x ) = x ^ { 2 } - x + 1$
B) $d ( x ) = x ^ { 2 } + 2 x + 2$
C) $\mathrm { d } ( \mathrm { x } ) = \sqrt { \mathrm { x } ^ { 2 } + 2 \mathrm { x } + 2 }$
D) $d ( x ) = \sqrt { x ^ { 2 } - x + 1 }$
