Given that 𝑓 is a function that maps 𝑋 to 𝑌, where 𝑋 is the set of negative nine negative six negative five and 𝑌 is the set of three, four, six, and nine and 𝑓 is the function with ordered pairs of negative nine four, negative six four, and negative five nine. Write the range of the function as a set.
The range of a function are the 𝑌 values. Here we have our function. And the 𝑌 values are four, four, and nine, and we only need to write four once even though it was repeated.
