If A = {2, 4, 6} and the function f(x) = x − 2, what is f(A)?

Answer and explanation

Correct answer: {0, 2, 4}

To find f(A), apply the rule f(x) = x − 2 to every element of A: f(2) = 0, f(4) = 2, and f(6) = 4. Therefore, f(A) = {0, 2, 4}. Option B is incorrect because it is the original set before applying the function. Exam tip: To find the image of a set, apply the function rule separately to each element of the set.
