Actually: None, largely because of improper formatting.

y = 2 () x would be an expo fn if you provided a base (b) and wrote this as

y = 2 (b) ^x " ^ " indicates exponentiation

y = x2 would be a power function (not an expo fn) if written y = x^2

y = (3) x would be an expo fn if written as y = 3^x
