Plz relation describes a function? a) {(0, 0), (0, 2), (2, 0), (2, 2)} b) {(−2, −3), (−3, −2), (2, 3), (3, 2)} c) {(2, −1), (2, 1), (3, −1), (3, 1)} d) {(2, 2), (2, 3), (3, 2), (3, 3)}

The answer is B

a function is a set of ordered pairs such that for each domain element there is only one range element the set of ordered pairs{(-2,-3),(-3,-2),(2,3)(3,2) is the only set that does not pair a domain elemnt with two or more range elements.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
