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

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

the answer is 0.071

good luck! : d
