Firstly, we can see that 2 goes into both terms of the expression, so we can factor it out like so: 2(x^2 - 16). Now we can spot a difference of two squares expression, as we have an x^2 minus a square number. Remember that the difference of two squares is in the format: (x+a) (x-a), and when expanded, gives you x^2-a^2. Using this information we square root 16 to find out the a value, so a=4. Therefore, your answer is B. 2(x+4)(x-4)

Answer:
A growth equation will have a base that is equal to or greater than 1.
f(x)=2* 
is a growth equation because 2 is greater than 1.
f(x)=.24* is a decay equation because .24 is less than 1.
