I understand the solution all the way to the final step. I don't understand why you have to multiply by 16. Can someone please explain this to me? I might be overthinking this......
Thanks!

Question: If g is a function defined for all x by g(x) = x^4/16 then what is the value of
g(2x) in terms of g(x)?

Ok - so if g(x) = x^4 / 16
then g(2x) is (2x)^4 / 16 = 16x^4 / 16 = x^4

This tells us that g(2x) is 16 times g(x)

Make any sense?
