Question

16 Let f(x) and g ) are function such that f () = x+5 and g(x) x+4, what is domain of f(x)+g(x)?​

Answer 1

Answer: all real numbers

Explanation:

I assume you meant to write:

• Let f(x) and g(x) be functions such that f(x) = x+5 and g(x) = x+4. What is domain of f(x)+g(x)?​

`f(x)+g(x)=(x+5)+(x+4)=2x+9`

Since this is a linear function, the domain is all real numbers.
