If the function \(f:\{1,2,3,4\}\to\{1,2,3\}\) is defined by \(f(x)=\min(x,3)\), what is its range?

Correct answer: \(\{1,2,3\}\)

For the domain values, \(f(1)=1\), \(f(2)=2\), \(f(3)=3\), and \(f(4)=3\). Hence, the set of distinct values actually attained by the function is \(\{1,2,3\}\), so option A is correct. Option B is the domain, not the range. Exam tip: To find the range, list all outputs and retain only the distinct values.
