Determine if the statement is true or false. If statement is false, make the necessary change(s) to produce a true statement.
If f (x) = 2^x then f(a+b)= f(a)+f(b)
=========================
f(a) = 2^a
f(b) = 2^b
----
f(a+b) = 2^a + 2^b
==================
Sub a+b for x:
f(a+b) = 2^(a+b)
Therefore, it is false.

.

The statement is FALSE.


To check that it is false, calculate  f(a+b)  and  f(a) + f(b)  at these values a= 1, b= 2.


The correct statement is  


    f(a+b) = f(a)*f(b).


Check it on your own.
