Please anwser this for me!!

Concept: Functions

In order to be a function, the values must satisfy the qualities stated below.No element in the domain and range of x corresponds to more than one representative value: ie x=2 and y= 8 but it cannot be that x=4 also.No element in the range can represent multiple values Hence we see in the chart that each x represent to a unique y and vise versa.So we determined that this is a function

The power of the root of the power of a variable can be written as a rational power by creating a rational exponent that is the product of the powers divided by the root. The rational exponent should be reduced to lowest terms. For example, the seventh power of the sixth root of the fifth power of x will be x^(7*5/6) = x^(35/6).
hope it helps
