Question

let f(x)=
x−−√

Is f(3+1)=f(3)+f(1)?

Answer 1

\[\sqrt{x}\]

Answer 2

Follow the same procedure as I followed in the previous question:

(1) Calculate f(3), f(1), f(3+1) i.e. f(4).

(2) Show that f(3)+f(1) \(\ne\) f(4)

Answer 3

is not equal

Answer 4

Yes they are not equal hence, f(3+1) is not equal to f(3) +f(1).

Answer 5

ok
