14. Sam is comparing two functions: a(x) = 20 x2 and k(x) = 5.2* to find out which one has
a greater output value as x get very large.
He notices that a(1)
=20 and a(2) = 80 while k(1) = 10 and k(2) = 20. He concludes that
as x. grows a will always have a greater value than the value of k.
Explain why Sam's conclusion is incorrect.
