I solved all of the question already but need to check the answer and need to see explanation

What is the natural domain of the function 3 f ( x ) = 2-2ex . V ( -00, 0) U (0, 00 ) O (0, 00) O R O The function does not exist for any X O ( -00, 0)\fWhich of the following functions is not one- to-one on its natural domain? O f (x) = 2x O g(x) = 2x +5 O h(x ) = 2x2 + 5 O p(x) = 2x3 + 5 O None of the above.If f is a one-to-one function such that f(2)=3 , what is f'1(3) ? O 0 Not enough information is given. If 1n(A) =2 and 1n(B) = 3 , what Is the value of 1n(e2 A2 B) ? 0 None of the above
