If f and g are tw

Answer :

Given: f and g be real valued functions defined as f (x) = 2x + 1, g (x) = x² + 1,

To find: f + g

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

So, f + g = (f + g)(x)

⇒ f + g = f(x) + g(x)

Substituting the corresponding equation, we get

⇒ f + g = 2x + 1 + x² + 1

⇒ f + g = x² + 2x + 2
