That is not possible at all. There are too many possible functions mapping
2 to 4, 3 to 9 etc.
You can, however, create a list of candidate functions and check your input
pairs (x,y) against each of those functions to see if any of them matches.
Short, unoptimized example:
functions = [
lambda x: x,
lambda x: x+1,
lambda x: x*x,
lambda x: x**3,
]
input = [(1,1), (2,2)]
for function in functions:
for x,y in input:
if function(x) != y:
break
else:
print "function", function, "matches"
