Write the function f as a set of ordered pairs. Give the domain and range of f.f(-1) = -10, f(1) = 5, f(4) = 10, f(9) = 8
A. f = {(-10, -1), (5, 1), (10, 4), (8, 9)}; D = {-1, 1, 4, 9}; R = {-10, 5, 8, 10}
B. f = {(-10, -1), (5, 1), (10, 4), (8, 9)}; D = {-10, 5, 8, 10}; R = {-1, 1, 4, 9}
C. f = {(-1, -10), (1, 5), (4, 10), (9, 8)}; D = {-1, 1, 4, 9}; R = {-10, 5, 8, 10}
D. f = {(-1, -10), (1, 5), (4, 10), (9, 8)}; D = {-10, 5, 8, 10}; R = {-1, 1, 4, 9}
