Answer:
Domain: {-10, -8, -6, -4}
Range: {-5, -4, -3, -2}
Explanation:
The domain is a set of all the x's. Here you were given points and the first number in the parenthesis is the x in (x, y). Sometimes they will give you a table or a graph. But domain is all the x's gathered together. I put them in order from small to big to be neat. There aren't any repeats here, but if there ever are repeats you don't have to list them multiple times, just once.
The range is all the y's in the points (x, y) its the second number. Gather all the y's in a set, that is the range.
