What is the first function? The second function?
What will be the output of the first function when the input is 2?
If the input becomes 5, what will be the output of (f o g)(x)? Verify the answer through calculation. Is it the same with the output of function machine?
What happens if you reverse the composition, like (f o g)(x)? Do you get the same result as (g o f)(x)? Do you think the order of functions matter?[br][br]
