Question

If f:R → R and g:R > R be two real function defined
by f(x) = 2x + 3 and g(x) = 3 – 2x. Then find
(f + g)(x) = ?​

Answer 1

Answer:

6

Step-by-step explanation:

Given :

f : R → R  and g : R → R

Also function is defined as :

f ( x ) = 2 x + 3

And g ( x ) = 3 - 2 x

We're asked to find ( f + g ) ( x ) :

= > ( f + g ) ( x ) = f ( x ) + g ( x )

Substituting values here we get :

( f + g ) ( x ) = 2 x + 3 + 3 - 2 x

= > ( f + g ) ( x ) = 6

Therefore , value of ( f + g ) ( x ) is 6.
