Question

Define the domain of the followingA) {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8}B) {3, -1, 2, 0, -2}C) {-3, -1, 1, 3, 6}D All real Numbers

Answer 1

The domain is a set tht contains all possible x-values in a relataion or a function. In this problem, we just need to know what the x-coordinates are to be able to identify the domain.

Let us first list down the coordinates of the given points. We have:

The x-coordinates are: -3, -1, 1, 3, and 6.

So the domain is: {-3, -1, 1, 3, 6}. The answer is option C.
