The Answer is

\begin{array} { l } f ( 2 ) = ( 2 - 2 ) ^ { 2 } + 5 = 5 \f ( a ) = ( a - 2 ) ^ { 2 } + 5 = 9 - 4 a + a ^ { 2 } \f \left( \frac { 1 } { a } ight) = \left( \frac { 1 } { a } - 2 ight) ^ { 2 } + 5 = \frac { 1 - 4 a + 9 a ^ { 2 } } { a ^ { 2 } }\end{array}

If f(x)=(x−2)2+5, find f(2),f(a), and f(1/a)\text { If } f ( x ) = ( x - 2 ) ^ { 2 } + 5 , \text { find } f ( 2 ) , f ( a ) , \text { and } f ( 1 / a ) If f(x)=(x−2)2+5, find f(2),f(a), and f(1/a)

$\text { If } f ( x ) = ( x - 2 ) ^ { 2 } + 5 , \text { find } f ( 2 ) , f ( a ) , \text { and } f ( 1 / a )$
