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: 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 subtracting functions f(x) from g(x), i.e., ⇒ (f-g)(x) = f(x)-g(x) Substituting the corresponding equation, we get ⇒ (f-g)(x) = √x-x

Answer»

Given: 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 subtracting functions f(x) from g(x), i.e.,

⇒ (f-g)(x) = f(x)-g(x)

Substituting the corresponding equation, we get

⇒ (f-g)(x) = √x-x
