If f and g are two real valued functions defined as f (x) = 2x + 1, g (x) = x2 + 1, then find.f – g

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 subtracting functions f(x) from 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 = 2x-x2
