Who is correct? Explain.

Tomas is correct, AC is opposite zB and BC is adjacent to B.

Iliana is correct, BC is opposite zB and AC is adjacent to
Both are correct because both AC and BC are opposite ZB.

Neither is correct because neither AC nor BC is opposite 2B.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
