If f is a function defined for all k by f(k) = k^5 /16, what is f(3k) in terms of f(k)?
Choose the correct choice from the following answers
A) 1/8 f(k)	B) 5/8 f(k)	C) 244 f(k)	D) 243 f(k)	E) 323 f(k)
f(k) = k^5 /16   f(3k) = (3k)^5/16 = 243 * k^5 /16 = 243 * (k^5 /16) = 243 f(k).   So answer is 243 f(k).
