Final answer:
The equation y² = 4(x - 2)² is not a function because there can be two values of y for a single x, hence the answer is False.
Step-by-step explanation:
The given equation y² = 4(x - 2)² is not a function because for a given value of x, there can be two different values of y (one positive and one negative), which violates the definition of a function that for each x, there must be exactly one y. In more formal terms, a relationship is a function if and only if each x-value is paired with exactly one y-value. Since the equation does not meet this criterion, the correct answer is False.
