The domain of f+g
WebOperations on Functions. Functions with overlapping domains can be added, subtracted, multiplied and divided. If f ( x) and g ( x) are two functions, then for all x in the domain of both functions the sum, difference, product and quotient are defined as follows. ( f + g) ( x) = f ( x) + g ( x) ( f − g) ( x) = f ( x) − g ( x) ( f g) ( x) = f ... WebFor the function f(x) = 1/x, the domain would be all real numbers except for x = 0 (x<0 or x>0), as division by zero is undefined. function-domain-calculator. en. image/svg+xml. Related …
