What is the range of the function \(g=\{(1,4),(2,6),(3,8),(4,10)\}\)?

Answer and explanation

Correct answer: {4,6,8,10}

The range of a function is the set of all second components of its ordered pairs. Here, the second components are 4, 6, 8, and 10, so the range is \(\{4,6,8,10\}\). Option B is the domain because it contains all the first components. Exam tip: in an ordered pair \((x,y)\), collect the y-values to find the range.
