Answer:
Domain: {-2, -1, 0, 1, 2}
Range: {-3, -2, 0, 1, 4}
Explanation:
Pre-Solving
We are given a graph with a couple of points plotted. We want to find the domain and the range.
The domain is the set of x values in which the graph exists. Likewise, the range is the set of y values in which the graph exists.
When we only have points, we just list out all the x values and all the y values of the points to get the domain and range respectively in order from least to greatest.
Solving
Let's list out the values of the points:
(-2, 1), (-1, 4), (1,4), (0, -3), (2, -2)
We can see therefore that the values of x (the domain) are therefore:
{-2, -1, 0, 1, 2}
And that the values of y (the range) are:
{-3, -2, 0, 1, 4} (if we have repeating values then we do not need to write them twice)
The answer is the bottom left option.
