2) For y = x", where n is a positive integer and x ER, which of the following statement is true? For all values of n, y is not a one-to-one function. For all values of n, y is an injective function. y is not a function If n is an even number, then y is not an injective function. If n is an odd number, then y is an injective function. 3) 16m If 4m - n= 0, then the value of ( + 27 mi is 2n g6m m
