I wanna ask for the definition for 'power function' say for example 2^X (2 to the power x) X^2 (x sq.) which one is a power function i've struggled for some time

No, that's the definition of an exponential function. As sa-ri-ga-ma mentioned (and I will generalize what the user said), a power function has the form , where can be any real number.
