Which of the following is a true statement about functions

The statement that is true about functions is:

            If f and g are function then,

       B.        (f+g)(x)=f(x)+g(x)

A)

Let us define f(x)=x² and g(x)=1

then we have:

and

Hence, we get:

Hence, option: A is incorrect.

B)

Option: B is always true.

 (f+g)(x)=f(x)+g(x)

C)

Let us define f(x)=x²

Then

and

Hence, we get:

        is not always equal to

D)

Let us suppose

Now,

and

Hence, we get:

              is not always equal to

the graph on the bottom right

it has the same slope and a different y-intercept

hope this : )
