Let f(x) = x^(2) , g (x) = 2x + 1 be ...

Let `f(x) = x^(2) , g (x) = 2x + 1 ` be two functions. Then find
(i) (f + g) (x) (ii) (f - g) (x) (iii) (fg) (x)

Text Solution

Verified by Experts

The correct Answer is:
(i) `(f+g)(x) = (x+1)^(2)`
(ii) `f-g(x) = x^(2)-2x-1`
(iii) `(fg)(x) = 4x^(2) +1+4x`
