Question 1127499
As it is written, it is not a function, since the same x-value has two y-values
If the first term is (0, 1), then the rule is (x, 3^x)

(2, 9) is 2^3+1 and (3, 27) is 3^3.  That isn't quite right, but if the first coordinate is the exponent, and the second coordinate is 3^x, it all comes together.
