Determine if a function is power function and what is the constant and power

The video tutorial explores whether a given function is a power function. Initially, it does not appear to be in the correct form, but by applying the rules of exponents, it can be rewritten using negative exponents. This transformation allows the function to fit the form K * X^A, confirming it as a power function. The tutorial concludes by identifying the constant K and the power A, solidifying the understanding of power functions.
