*not a lot of time* me! i am confused as to what i do, i was not given the best worded examples and directions.

The answer is the first option. Domain: {-4,0,8}; Range: {2,1,5,10}

Explanation:

You need to know the definitions of domain and range.

Domain is the set of input values. That is those values for which the relation is defined or the values that the independent variable can have. The possible values for x.

So, take the first coordinate of the ordered paris. That is {-4,0,8}

Range is the set of output values. The values that the function takes. The values of the dependent variable. The possible values for y.

So, take the second coordinate of the ordered pairs. That is {2, 1, 5, 10}
