question 157

Multiple Choice

A one-to-one function f is given. $\text { Find } \mathrm { f } ^ { - 1 } ( \mathrm { x } )$ and graph fwith a solid line and $f ^ { - 1 } ( x )$ with a dotted line on the same axes.
- $f ( x ) = \sqrt { x + 5 } , x \geq - 5$

• A) \(f ^ { - 1 } ( x ) = x ^ { 2 } + 5 , x \geq 0\)
• B) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \mathrm { x } ^ { 2 } - 5 , \mathrm { x } \geq 0\)
• C) \(f ^ { - 1 } ( x ) = x ^ { 2 } + 5 , x \geq 0\)
• D) \(f ^ { - 1 } ( x ) = - x ^ { 2 } + 5 , x \leq 0\)
