Let f(x) = √x and g (x) = x be two functions defined in the domain

1.	Let f(x) = √x and g (x) = x be two functions defined in the domain R+∪ {0}. Find (f + g) (x).
Answer» Given: f(x) = √x and g (x) = x two functions defined in the domain R ⁺ ∪{0}, To find: (f + g)(x) Explanation: this can be obtained by adding functions f(x) and g(x), i.e., ⇒ (f + g)(x) = f(x) + g(x) Substituting the corresponding equation, we get ⇒ (f + g)(x) = √x + x

Answer»

Given: f(x) = √x and g (x) = x two functions defined in the domain R ⁺ ∪{0},

To find: (f + g)(x)

Explanation: this can be obtained by adding functions f(x) and g(x), i.e.,

⇒ (f + g)(x) = f(x) + g(x)

Substituting the corresponding equation, we get

⇒ (f + g)(x) = √x + x
