Answer
a. A∩B
b. A∩B
c. A∩B \ $g(x)\ne 0$
Work Step by Step
$f(x)$ has Domain A and $g(x)$ has domain B
a. Domain of f+g includes all values of x within Domain A and B, so Domain: A∩B
b. Domain of fg includes all values of x within Domain A and B, so Domain: A∩B
c. Domain of f/g deals with $g(x)$ not being able to equal 0, so Domain is A∩B \ $g(x)\ne 0$
