If f:{1,2,3} → {1,4,9} is defined by f(x) = x², which are the ordered pairs of f?

Answer and explanation

Correct answer: {(1,1),(2,4),(3,9)}

A function is represented by ordered pairs (x, f(x)), where the first component is an element of the domain and the second component is its uniquely assigned image. The rule here is f(x) = x². Substituting each domain element gives f(1) = 1² = 1, f(2) = 2² = 4, and f(3) = 3² = 9. Therefore the graph or ordered-pair representation is {(1,1),(2,4),(3,9)}, so option A is correct. Option C reverses the input-output direction, treating image values as first components. Option B uses values that do not follow x², and option D reverses or rearranges the outputs without applying the stated rule. Every domain element appears exactly once, confirming that this is a function.
