Find the inverse of function f. f(x) = 1/2x +7 /
f(x)=(1)/(2)x + 7

A.) f^-1 (x) = x -7 /
$f^(-1)\:\left(x\right)\:=\:x\:-7\:\:$
B.) f^-1 (x) = 2x - 7 /
$\:f^(-1\:)\left(x\right)\:=\:2x\:-\:7$
C.) f^-1 (x) = 2x- 14 /
$\:f^(-1\:)\left(x\right)\:=2x-\:14$
D.) f^-1 (x) = 2x + 1/7 /
$f^(-1\:)\left(x\right)=2x\:+\:(1)/(7)\:$
