A. State the domai and ranga. 1. y find the inverse and state the domamamd Tange of f Domain: Rang Graph and sraph. Solution f(x) = 3+ 2^x Domain : ( - inf , inf) Range : ( 2 , inf ) Inverse : y = 3 +2^x Plug x= y and y = x: x = 3 + 2^y (x -3) = 2^y take ln on both sides: ln( x-3 ) = yln2 y = ln2( x-3) f^-1(x) = ln2( x-3) Range : ( - inf , inf) Domain : ( 2 , inf ).
