If \(f(x)=|x|\) and \(A=\{-2,0,3\}\), what is the image set \(f(A)\)?

Correct answer: \(\{0,2,3\}\)

Apply the function to each element of \(A\): \(f(-2)=|-2|=2\), \(f(0)=0\), and \(f(3)=3\). Hence, \(f(A)=\{2,0,3\}=\{0,2,3\}\). Option B is just the original set \(A\), not its image under \(f\). Exam tip: To find an image set, evaluate the function for every element of the given set and list each resulting value only once.
