Question

Give the domain and range. domain: {2, 0, 2}, range: {1, 0, 1}

Answer 1

Domain: {0, 2}

Range: {0, 1, 1}

When dealing with the domain, remember that no numbers can repeat in the domain so if there is more than one of the same number, we only list it one.

When dealing with the range, it's ok if numbers repeat because it's the y-value not the x-value.
