Question

Find the domain and range of the relation, and determine whether it is a function,

{(1, -1), (2, -2), (3, -3), (4-4), (5. --5)}
A domain: {-1, -2, -3, -4,-5); range: {1, 2, 3, 4, 5), function
O B. domain: {1, 2, 3, 4, 5); range:{-5, --4, -3, -2, -1); not a function
C domain: {-2, -1, 1, 2, 3}; range:{-5, -4,-3,4,5), not a function
D. domain: {1, 2, 3, 4, 5); range: {-5, -4 -3, -2, -1} function

Answer 1
