Explanation & Answer
Thank you for the opportunity to help you with your question!
(f + g)(x) = f(x) + g(x) = x − 2+ x^2
domain of
(f + g)(x). = (-INFINITY to + INFINITY)
(f - g)(x) = f(x) - g(x) = x − 2- x^2
domain of
(f - g)(x). = (-INFINITY to + INFINITY)
(fg)(x) = f(x)*g(x) = (x − 2) x^2= x^3- 2x^2
domain of
(f g)(x). = (-INFINITY to + INFINITY)
( f/g )(x)= f(x)/ g(x)= (x − 2) / x^2
domain of
(f g)(x). = (-INFINITY to -1, 1 to + INFINITY ) zero is not included in domain
